Surgical treatment of carotid body tumor: case report and literature review
Tao Luo,Chao Zhang,Ya-Chan Ning,Yong-Quan Gu
老年心脏病学杂志(英文版) , 2013,
Abstract: Carotid body tumors (CBT) are rare chemical receptor tumors. We report nine cases of CBT who were diagnosed at our center during 2004 to 2008 with a literature review. Of these nine patients, eight underwent complete resection, one received palliative resection due to the malignant nature of the tumor, and the other one refused surgery. No perioperative mortality and stroke occurred. During a mean follow up of 2.2 years, no deaths related to CBT occurred. Surgical treatment for CBT is relatively safe. The surgeon should be careful to maintain the integrity of carotid artery, and prevent cerebral ischemia and cranial nerve injuries in order to improve outcome.
Aortic Deceleration Injury Treated by Endograft: A Case Report with 11-Year Followup
Zhi-Wei Hu,Wang-Zhong Gao,Yong-Quan Gu,Bing Chen,Guang-Chang Zhu,Wei-Tao Liang,Ya-Chan Ning
Case Reports in Vascular Medicine , 2012, DOI: 10.1155/2012/608358
Abstract: Aortic deceleration injury is a common and critical condition following automobile accident with high fatality. The survivors complicated with associated serious injuries are even rare and definitive treatment is required. A 37-year-old male patient had both aortic blunt injury and coronary artery injury after a frontal car collision. After failed coronary artery percutaneous transluminal angioplasty (PTA) and deteriorated aortic lesion, the ruptured aorta was subsequently successfully treated by us with a self-made individualized endograft. The endograft was well in position and the patient functioned well in 11-year followup. With the development of endograft and technique, the endovascular treatment may be an option for patients with complicated aortic blunt injury. Yet careful patient selection and the long-term followup are essential. 1. Background Aortic deceleration injury is a common and critical condition following automobile accident with high fatality. The survivor of aortic combined with cardiac injury, even coronary artery injury, are fewer. For the survivors of the initial injury, a majority will die without definitive treatment. Major operations are mandatory for some of the patients. However, the patients complicated with associated serious injuries. Cardiac injury, delaying aortic repair, was suggested, as the emergence of endovascular treatment with minimal invasive advantage, and endograft may be an option for this group of patients. Here is such a patient treated with endovascular treatment with 11 years followup. 2. Patient On April 16, 2001, a 37-year-old driver was admitted to the Department of Cardiology from emergency service. He had a head-on care collision a week earlier without treatment, which caused him chest tightening, pain, breathlessness, and a transient unconsciousness. His vital sign was stable (pulse rate 80 beat/min, respiratory rate 20 times/min, blood pressure 140/70?mmHg) and no signs of visible injury were found. But a CT scan revealed a widening mediastinum and a massive left pleural effusion. He had undertaken medical treatment and monitoring. On the seventh day of admission, he complained a severe chest pain. Electrocardiogram showed a ventricular fibrillation. A defibrillation was successful, but the ST segment remained elevated on the lead V1–V5, with cardiac enzyme: CK3 974?U/L and CK-MB 469?U/L. Echocardiography showed no contraction of the anterior cardiac wall and ejection fraction (EF) 36%, indicating a myocardial infarction. Coronary angiography revealed a disruption of the proximal left anterior

(E)-N-[(5-Methyl-2-furyl)methylene]-3-nitroaniline
Ya-Ning Guo
Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536809007107
Abstract: The asymmetric unit of the title compound, C12H10N2O3, contains two crystallographically independent molecules, in which the furan and benzene rings are oriented at dihedral angles of 46.09 (3) and 39.98 (3)°. In the crystal structure, weak intermolecular C—H...N hydrogen bonds link the molecules into chains running nearly parallel to the a axis.
後設資料註冊中心現況發展之研究 A Review on Metadata Registries Development
Ya-ning Chen
Journal of Educational Media & Library Sciences , 2004,
Abstract: 本文研究目的在探討國際上現有metadata registries的設計與發展,以達成metadata標準相關資訊的再利用與互通性。本文採取個案研究法,以數位圖書館metadata為範圍,選取12個研究樣本進行分析。本文研究發現主要有五項:第一,多數metadata registries (MDRs)已臻至機讀的階段。第二,涵蓋標準數量上有單一與多數兩種。第三,描述對象除了以典藏品為主外,也擴及至人與機構;資訊單元(information granularity)主要包含標準、元素與控制詞彙三個層級。第四,所有MDRs皆對metadata元素間的關係加以標引,只有一些針對標準與元素間的關係予以建立,甚至展延至控制詞彙,而這些MDRs通常不採用ISO/IEC 11179。第五,發展MDRs有兩大取向,一是採取資料元素方式,通常採用ISO,資料描述十分詳盡;二是採取metadata元素方式,資料描述十分簡易。 How to reuse and interoperate the information between various metadata standards becomes an important issue for digital library projects and metadata registries (MDRs) are employed as a workable approach around the world. This paper aims to take a review on current development of MDRs, by adopted case study as research methodology to examine twelve cases. Consequently, five findings are offered in the following:1. most MDRs can be generalized into machine readable MDRs. 2. Some MDRs include elements from a single standard, and some from multiple ones. 3. MDRs focus on cultural heritage objects, but now has been expanded to include institutes and users.Information granularity that MDRs handle is generalized into metadata standard,element and encoded scheme. 4. Relationships between elements are common to all practices, but relationships between standards, elements and encoded schemes are not applied to all. 5. The approach of MDRs description is toward two types: data elements and metadata elements. The former one has a preference for comprehensive description,and the latter one is toward appropriate description for practical requirements and is separated into various identities instead of all in one.
建立圖書館自動化系統的標準評鑑模式 Building a Standard Evaluative Model for Library Information System
Ya-ning Chen
Journal of Educational Media & Library Sciences , 2002,
Abstract: 無 Library automation has been developed for 30 years nearly in Taiwan since 1973. after a serious literature review on the topic of library automation evaluation in Taiwan, only several papers have been discussed, but most for them focus on case study. This paper aims to construct a standard evaluative model for library automation system both for selection and usage. The proposed model is composed of four key components by follows: identifying the past and current trends, four facets and related content of evaluation model, evaluation principles, methods and criteria, as well as the model is exemplified into four stages. Finally, additional five issues are raised as a conclusion: cost benefits and efficiency, risk distributed, partnership relation, and librarians' skills and ability.

Robust Key Agreement Schemes
Terence Chan,Ning Cai,Alex Grant
Mathematics , 2009,
Abstract: This paper considers a key agreement problem in which two parties aim to agree on a key by exchanging messages in the presence of adversarial tampering. The aim of the adversary is to disrupt the key agreement process, but there are no secrecy constraints (i.e. we do not insist that the key is kept secret from the adversary). The main results of the paper are coding schemes and bounds on maximum key generation rates for this problem.
