The conventional non-invasive and invasive technique have limitations in evaluating cardiac prosthetic valves and artificial valves. We have used continuous wave Doppler echocardiography to evaluate 48 patients with tissue and mechanical mitral valves implanted within 4 months prior to examination. The results are as follows. 1) Of these patients, male are 28. The mean ages of male are 35.60 (yr) and female are 41.82. 2) The differences of peak and mean velocities of prosthetic acardiac valves between male and female are not significant, but the differences of valvular size between male and female are significant(male:31.00±1.30(mm), female:29.36±2.11, p<0.01). 3) The difference of size and flow velocities between mechanical (Edwards-Duromedics) and tissue(Ionescue-Shiley) valves are not significant, but the ages of patients with mechanical valves are significantly lower than tissue valves(mechanical valve; 34.05±11.28, tissue valve; 43.62±11.26, p<0.01). 4) The differences of flow velocities between mechanical and tissue valves, sizes of which are 31mm, are significant statistically (peak velocity; 130.15±24.59 vs 110.00±19.41, mean velocity; 74.49±23.14 vs 51.38±12.71, p<0.01). 5) The sizes of valves are larger, the peak and mean velocities are lower, but it is not significant statistically. The results indicated that Doppler echocardiography is a useful method for evaluating function of prosthetic valves.

The object of this study is to obtain a fundamental data on the food and nutritive components of wild fresh water Mud-turtle, Amyda-sinensis, propduced in Korea.For this purpose, the food components in each portion such as the layer of fat, blood and total flesh were investigated and compared by the distinction of sex, respectively.Th results obtained are summarized as follows : 1.Proximate compositions of total flesh between the female and male were nearly the same on the whole, as the contents of moisture, crude protein, crude fat, total sugar and crude ash were 78.4-80.1%, 16.8-18.7%, 1.5-1.6%, 0.3-0.4%, 1.1%, respectively. Protein-N occupied 89%, 91% of total nitrogen content, respectively. 2.The analysis of free amino acids showed that histidine, methionine and arginine were major amino acids in the flesh extract of female, having 32.7% (546.30mg%), 28.8%(481.44mg%),19.7%(329.72mg%) on dry basis, and that histidine, methionine, serine were major in the male, having 34.6% (360.45mg%),28.6% (298.39mg%),8.2% (85.18mg%) of total free amino acid contents, respectively. While the other free amino acid contents except threonine and proline in trace of undetected amount were relatively poor by the content ratio of 0.2-5.3%. 3.The content of lysine in total flesh of the female and male seemed to be marked differences, being 13.5%(2415.73mg%) and 9.3%(1465.37mg%) respectively, but the other amino acid compositions of the female showed similar tendency to that of the male without significant differences. The major amino acids were glutamic acid (16.3-17.7%), lysine (9.3-13.5%), aspartic acid (7.6-8.7%) leucine (7.7-8.3%), alanine (5.8-6.2%) and arginine (5.6-6.0%) occupied 56.2-56.5% of total amino acids, but such amino acid contents as proline, threonine glycine, valine, phenylalanine, serine, isoleucine, tyrosine, methionine and histidine were low in order, while cystine and tryptophan were least amount. The essential amino acid content of 8 kinds occupied 38.0-43.2% (2471.92-2832.72mg/gN) of total amino acids. 4.Among the 9 kinds of minerals analyzed such as total flesh and blood, mineral compositions in the female showed similar to the pattern in the male. Such macrominerals as potassium, magnesium, sodium and phosphorus contents in flesh were absolutely predominant being more than 98.0% (498.5-521.6mg%), these four elements in blood also occupied 92.7-94.1% (498.1-551.6mg%) of total minerals, while iron content of micromineral in blood 5.3-6.8% (31.0-36.4mg%). 5.Fatty acid compositions in total lipid were different considerably by the distinction of sex and each portion except layer of fat. The major fatty acids of flesh in the female and male were shown to be C18 : 1(1425.7%), C16 : 0(13.5-18.6%), C18 : 3(9.0-17.4%), C16 : 1(13.4-16.4%), and particulary C18 : 2(20.0%), C14 : 1(16.5%) in the male.In fresh blood of the female and male, C18 : 1(16.3-36.7%), C16 : 1 (16.2-18.5%), C18 : 3 (13.7-17.3%), C16 : 0(8.5-9.6%) were the most abundant fatty acids, and particulary C14 : 1(10.1%), C18 : 2(9.1%) in the male. In the layer of fat, the major fatty acids were C18 : 1(25.2-28.0%), C16 : 0(17.2-18.3%), C16 : 1 (15.8-17.0:7), C18 : 3 (10.5-11.6%) and C18 : 2(8.8-9.7%).Total lipids consisted of 18.3-32.5% of saturated fatty acids, 42.6-60.6% of monoene and 19.2-29.2% of polyene acids to total fatty acids, respectively, and P/S ratio in each fortion were in sphere of 0.7-1.2.

배성균(Sung-Kyun Bae),김영근(Young-Keun Kim),권혁주(Hyeok-Ju Kwon),이양선(Yang-Sun Lee) 한국멀티미디어학회 2006 한국멀티미디어학회 학술발표논문집 Vol.2006 No.1

EVM(Embedded Virtual Machine) 은 ISO/IEC C++ 와 SUN사의 Java 등의 객체지향 언어를 수용할 수 있는 임베디드 가상기계 솔루션이며, SIL(Standard Intermediate Language)은 EVM의 종간언어로 객체치향 언어와 순차적인 언어를 위한 연산 코드 집합을 갖고 있다. 기존의 객체지향 C++ 컴파일러는 C++ 프로그램을 목적기계의 코드로 변환하여 실행한다. 이러한 문제를 해결하기 위해 본 연구팀은 EVM을 개발하면서 목적기계의 코드가 아닌 플랫폼에 독립적인 스택기반의 가상기계 코드를 생성하는 C++ 컴파일러를 개발하였다. 본 논문에서는 C++ 컴파일러가 생성한 중간 언어인 SIL 코브를 3-주소 코브 형태의 재 표현된 C++ 프로그램으로 변환하는 역컴파일러(Decompiler) 시스템을 설계하고 구현하였다. 역컴파일러가 생성한 C++ 프로그램의 실행을 통해 SIL 코드가 올바르게 생성되었는지를 확인할 수 있으며, 최적화된 SIL 코드의 생성을 위한 시뮬레이션을 제공한다. 또한 프로그램에 담겨진 의미를 어셈블리 형태를 지닌 SIL 코브에 비해 소스 레벨로 쉽게 분석할 수 있다는 장점이 있다.

목적 : 의료기관의 범유행 인플루엔자에 대한 효과적인 대비를 위한 훈련방법으로서 의료기관-바탕 탁상훈련 (hospital based tabletop exercise)의 유용성과 순응도를 평가하기 위해서 시행되었다. 재료 및 방법 : 탁상 훈련은 부산대학교 병원에서 시행되었으며 병원의 주요의사결정권자 및 주요부서 대표자, 실무자 42명이 지휘부, 진료부, 지원부 3그룹으로 나뉘어 훈련에 참가하였다 탁상훈련의 시나리오는 의료기관의 자체 훈련을 위해서 고안하였으며 현재 동남아에서 유행하고 있는 H5N1 인플루엔자가 국내에 처음으로 유입되어 확산되는 과정에서 의료기관에서 발생할 수 있는 상황을 3가지 모듈로 구성하였다. 훈련 평가는 훈련 전후에 각각 익명의 설문조사를 시행하였다. 결과 : 훈련에 초청된 참여자 42명 중 37명(88%)이 실제 당일 훈련에 참여하였다. 훈련에 참여한 37명의 직원 중에서 훈련 전 시행한 설문에 27명(73%)이 응답하였다. 훈련 전 정가에서는 훈련을 통해 획득하고 싶은 지식이나 기술의 우선 순위를 물었으며, 참여자들이 가장 중요하다고 생각하는 항목은 대유행인플루엔자 바이러스에 대한 지식 향상 22%, 병원 각 부서가 취해야 할 계획 및 의사소통과 관련된 지식 향상 19%, 지역사회 병원들 간의 상호협력을 향상시킬 전략 계발이 19%이었다. 그룹토의 동안에는 환자의 조기 발견 이후 대응에 대한 토론이 많았지만, 구체적인 부분이 미흡하였고, 대유행 인플루엔자에 대한 기본적인 이해가 부족하였다. 훈련에 참여한 37명의 직원 중에서 훈련 후 시행한 설문에 21명(57%)이 응답하였다. 훈련 후 평가에서 탁상훈련의 전반적인 만족도에 대한 질문에서 81%가 만족하였다고 답변을 하였고, 새로운 것을 배우는데 유용했는가 대한 질문에도 86%가 유용했다고 답변하였다. 결론 : 탁상훈련은 의료기관의 대유행인플루엔자 대비에 효과적인 훈련방법이라고 생각되며 훈련을 통해 의료기관 내의 여러 부서들이 각 의료기관의 특성에 맞는 현실적이고 실제적인 대비 계획을 수립하는데 도움을 줄 것으로 기대된다. 그러나 향후 토른 촉진, 구체적인 결과에 도달을 유도할 수 있는 질문, 끼워넣기 개발, 적절한 시간 등에 대한 연구가 필요할 것으로 생각된다. Background : To evaluate the usefulness and compliance of a hospital-based tabletop exercise in setting of pandemic influenza in hospitals. Materials and Methods : Tabletop exercise was held in Pusan National University Hospital and forty two hospital employees were invited to participate in the exercise. The scenario for hospital-based tabletop exercise was designed. It consisted of three modules, which simulated the influx and outbreak of H5N1 influenza that was epidemic in Southeast Asia. Pre-, post-exercise surveys were completed by anonymous questions. Results : Thirty-seven (88%) of 42 invited participants attended exercise. AII members of the administration group and the ancillary services group participated. But, only 77% members of the clinical services group participated. In pre-exercise survey, priorities of eight goals regarding skills and knowledge during exercise were inquired., The highest priorities pointed out by the respondents were "Increase the knowledge of pandemic influenza" (22%), "Development of strategies for optimal communication among employees within specific department" (19%) and "Development of strategies for improved coordination between facilities within the health system" (19%). Twenty-one (57%) of participants completed the post-exercise surveys. At post-exercise surveys, 81% of the participants stated that the tabletop exercise was extremely or very useful, 86% of the participants also stated that it increased their knowledge of pandemic influenza. Conclusion : Tabletop exercise is an effective modality for increasing pandemic influenza preparedness in hospitals, and this method is useful for guiding preparedness activities within the hospital environment. Further studies to determine the appropriate method of discussion, questionnaire, duration of exercise and injection are needed.

Role of the methionine sulfoxide reductase MsrB3 in cold acclimation in Arabidopsis.

Kwon, Sun Jae,Kwon, Soon Il,Bae, Min Seok,Cho, Eun Ju,Park, Ohkmae K Japanese Society of Plant Physiologists 2007 Plant & cell physiology Vol.48 No.12

<P>Methionine residues of proteins are a major target for oxidation by reactive oxygen species (ROS), which are generated in response to a variety of stress conditions. Methionine sulfoxide (MetO) reductases are present in most organisms and play protective roles in the cellular response to oxidative stress, reducing oxidized MetO back to Met. Previously, an Arabidopsis MetO reductase, MsrB3, was identified as a cold-responsive protein. Here we report that MsrB3 functions in the process of cold acclimation, thus contributing to cold tolerance. In contrast to normal, wild-type plants, msrb3 mutant plants lost the ability to become tolerant to freezing temperatures following cold pre-treatment. Furthermore, when exposed to low temperature, msrb3 plants exhibited a larger increase in MetO and H(2)O(2) content and electrolyte leakage compared with wild-type and MsrB3 transgenic plants. It is also shown that MsrB3 is localized at the endoplasmic reticulum (ER). We propose that MsrB3 plays an important role in cold tolerance by eliminating MetO and ROS that accumulate at the ER during cold acclimation.</P>

Myoepithelial carcinoma with contralateral invasive micropapillary carcinoma of the breast

Sun Young Kwon,Young Kyung Bae,Jihyong Cho,Sun Hee Kang 대한외과학회 2011 Annals of Surgical Treatment and Research(ASRT) Vol.81 No.3

Adenomyoepithelioma (AME) is a rare benign tumor composed of myoepithelial cells (MECs) which are located beneath the epithelial cells of exocrine glands, especially in breast and salivary glands. These tumor cells show biphasic proliferation of epithelial and MECs. Malignant AME is characterized by distant metastasis, local recurrence, cytologic atypia, high mitotic activity and infiltrating tumor margins. A 51-year-old woman presented with an 8 months growth in the left breast. She underwent core-needle biopsy and consecutively mammotome assisted biopsy at a local clinic. After resection, she complained about re-growing remnant lesion and a newly developed solid mass in the right breast. Finally, the remnant mass in the left breast was diagnosed with myoepithelial carcinoma. Concurrently, contralateral breast mass was diagnosed with invasive micropapillary carcinoma. Herein we report an unusual case of synchronous myoepithelial carcinoma and invasive micropapillary carcinoma of the breast with a review of literatures.
