Rhabdomyolysis is a biochemical and clinical syndrome caused by lysis of skeletal muscle cell and release of muscle cell contents into the circulation. In addition to traumatic cause, various nontraumatic causes have been reported. Rhabdomyolysis has frequently been associated with seamy aspects of life and society: alcoholic abuse, drug addiction, sadistic drill exercise, war events and attempted suicide. The abuse of alcohol causes many hazards in many organs. One of these is acute alcoholic myopathy that may present as a fulminent syndrome of muscle pain and tenderness associated with rhabdomyolysis and acute renal failure. Because the prognosis of adequately treated rhabdomyolysis is excellent, early recognition and prompt management are essential in emergency situation. We experienced two typical cases of alcohol-induced rhabdomyolysis with acute renal failure and report these cases with literature review.

전자책 (e-Book)산업은 디지털 컨텐츠 분야에서 가장 주목받는 새로운 산업으로 떠오르고 있다. 그러나, 기존의 전자책은 표준화된 형식에 의해서 작성되지 않을 뿐 아니라 다운로드 방식에 의하여 사용자의 단말기에 컨텐츠를 내려받기 때문에 저작권에 심각한 문제를 야기시키고 있다. 본 연구에서는 전자책의 컨텐츠를 XNL 형식으로 작성하고 그 내용을 다운로드방식이 아닌 스트리밍 방식으로 처리하여 단말기에서 전용 브라우저를 통하여 컨텐츠를 검색함으로써 전자책 컨텐츠의 표준화와 저작권 문제를 다소간 해결하는 방안을 제시한다. XML has become a very important emerging standard because of its flexibility and universality. Many application programs are actively developed to handle information in XML formats. We propose and implement a generic architecture for processing electronic books (e-Book) where book contents are in XML format. Our new e-Book contents are displayed in page-on-demand techniques comparing with file-download scheme of previous technique. This technique is suitable when considering intellectual property issues.

Phenobarbital is a long-acting barbiturate causing generalized depression of neuronal activity in the brain. Its effect is primarily achieved through enhanced GABA-mediated synaptic inhibition. Its use as an antiepileptic agent was first described in 1912. Before the introduction of phenytoin, phenobarbital is used as sedative-hypnotics. It is used for the treatment of epilepsy and status epilepticus. All barbiturates, including phenobarbital, have a high potential for abuse. They were frequently used for suicide attempts in the past, but they have in large part been replaced by benzodiazepines. The onset of symptoms depends on the drug and the route of administration. Mild to moderate barbiturate intoxication resembles ethanol inebriation with slurred speech, ataxia, and lethargy. Severe acute barbiturate intoxication is life threatening. Early deaths are generally cardiovascular-related. Hypotension, shock, pulmonary edema, and cardiac arrest that occurs with large doses are caused by depression of central sympathetic tone and as well as by direct depression of cardiac contractility. The potentially fatal oral dose of phenobarbital is 6-10g. We describe an 23-year-old woman with pulmonary edema, and cardiac arrest ingestion of 18grams of phenobarbital. She was completely recovered by successful cardiopulmonary resuscitation and homoperfusion. We report a case with literature review.

The wear specimens of M.E.F. steel were conducted by Amsler type abrasive test machine under sliding ratio 9 09%. The relationship between weight loss ratio of wear, rolling life and scanning electron microscope investigation of micro wear surface was investigated during the test. The results of the experiment are summarized as follows. The amount and the weight loss ratio of the rolling wear are decreased when tensile strength is high and the amount of rolling wear of M E F. steel is lower than that of raw materials. As the ferrite grain size of M E F. steel is small, the amount and the weight loss ratio of the rolling wear are decreased. The amount of rolling wear is increased with increasing rolling revolution and wear of dual phase steel under dry rolling condition is characterized by three modes, initial, stationary wear and abnormal wear. Abnormal wear is caused by pitting occurrence on the exfoliation of sub-surface layer because of compression, shear, sliding of this wear surface. The wear surface condition is getting better as the ferrite grain size is getting smaller, which is caused by the promotion of the second phase sketetal strength.

The objective of this study was to help decision-makers to be able to make a decision on a social tourism investment, based on the reasonable estimate standard. This was possible by introducing the estimate method for the effectiveness of investment on social tourism project and by using this method on the analysis of the alternative investment projects. For the analysis and estimate of welfare tourism investment, the advanced cost-benefit model was developed, based on the previous traditional cost-benefit analysis. This new cost-benefit model supplemented the weakness fo traditional cost-benefit model by utilizing the concept of total-social-benefit and total-social-cost.

본 연구는 반추가축사료의 단백질 이용효율을 높이기 위한 방안으로 국내 사료회사에 주로 이용하고 있는 단백질 사료의 반추위내 분해단백질(RDP)과 비분해단백질(UDP) 및 소장에서도 흡수되지 않는 이용불능단백질 함량들을 측정하기 위하여 실시하였다. 반추위와 십이지장에 캐뉼라를 부착한 젖소에 in sacco와 mobile bag 기술을 이용하여 여러 가지 원산지와 종류가 다른 단백질 원료사료의 반추위내 분해율과 소장 내에서의 이용성을 평가한 결과는 다음과 같다. 1. 나일론백을 이용한 반추위내 단백질 분해율을 측정한 결과 UDP가에 있어 우모분(78.0), 옥수수글루텐(75.2), 어분(64.9), 알팔파 펠렛(46.6), 면실박(44.9), 채종박(42.9), 캐놀라박(41.4), 참깨박(40.6), 대두박(39.2), 해바라기씨박(30.4) 순으로 나타났다. 2. 11가지 사료를 mobile bag을 이용하여 전장 소화율을 측정한 결과 건물 소화율은 49.1%(야자박)에서 97.5%(대두박)까지, 단백질 소화율은 71.5%(우모분)에서 99.6%(대두박), 소화 가능한 UDP 함량은 63.5%(대두박)에서 99.0%(우모분)의 범위를 나타내었다. 3. 우모분, 알팔파 펠렛 및 어분 등과 같이 소화 가능한 UDP 함량이 낮은 것은 비소화성 섬유소에 결합되어 있는 ADF-N 함량도 다른 시료보다 매우 높았다. 4. 알팔파 펠렛은 지나친 열변성으로 인해 ADF-N 함량이 사료들 중에서 가장 높았으며 이로 인해 전장 단백질 소화율은 물론 소화 가능한 UDP함량도 매우 낮은 것으로 나타났다. This study was conducted to estimate the amount of rumen degradable protein(RDP), undegradable rumen dietary protein(UDP) and digestible UDP, thereby utilizing dietary protein sources in ruminant diets more effectively. Ruminally and intestinally cannulated cows were used for in sacco and mobile bag techiniques to estimate ruminal degradability and intestinal availability of protein feed ingredients. The results obtained were as follows; 1. Based on in sacco data, UDP values were ranked as feather meal(78.0), corn gluten meal(75.2), fish meal(64.9), alfalfa pellet(46.6), cottonseed meal(44.9), rapeseed meal(42.9), cannola meal(41.4), sesame oil meal(40.6), soybean meal(39.2), sunflower oil meal(30.4). 2. Actual degradabilities in total digestive tract for 11 selected feeds varied from 49.1%(palm kernel meal) to 97.5%(soybean meal) for DM and from 71.5%(feather meal) to 99.6%(soybean meal) for protein, and digestible UDP contents ranged from 63.5%(soybean meal) to 99.0%(feather meal). 3. Feather meal, alfalfa pellet and fish meal, containing low amount of digestible UDP, also have high concentrations of acid detergent fiber bound N(ADF-N) which is unavailable for animals. 4. Alfalfa pellet has highest in ADF-N concentrations among protein ingredients due to extreme heat damage, thus protein degradability in total digestive tract was also very low.

Background: The end-tidal carbon dioxide tension(ETCO₂) is defined as a partial pressure of carbon dioxide at the end of an exhaled breath. The purpose of this study is to determine the correlation between ETCO₂and arterial carbon dioxide tension(PaO₂) in nonintubated patients with respiratory distress in emergency department(ED). Methods: A prospective non-blind study was performed in ED of our university hospitals. Participants included all nonintubated adult patients with respiratory distress requiring arterial blood gas analysis. ETCO₂was measured with a capnography monitor during tidal volume breathing. ETCO₂were recoreded at the time of arterial blood gas sampling. The correlation between ETCO₂and PaCO₂was analyzed in all patients and in subgroups by simple linear regression. Results: Sixty patients were enrolled. In all patients, ETCO₂was 5.72mmHg lower than PaCO₂and correlated well with PaCO₂(r²=0.716). ETCO₂correlated best with PaCO₂in patients who were either acidotic or non-smoking. Conclusion: ETCO₂correlate well with PaCO₂in nonintubated patients with respiratory distress in ED. ETCO₂may be sufficient to reflect PaCO₂in selected patients and obviate the need for repeat arterial blood gas determination.
