The Application of Chinese Traditional Architectural Symbols in Modern Architecture

随着建筑设计对于本土化与地域性关注的增加,传统建筑符号在现代建筑中的应用也引起了广泛关注。本文从符号学的基本理论、建筑符号的意义、建筑符号的运用与创新以及传承与发展四个方面来讨论中国传统建筑符号的意义。然后对于中国传统建筑符号的应用与发展进行评析,以期使中国传统建筑符号在现代建筑中重新焕发生机。With the increase of localization and regionalism in modern architectural design, the application of the traditional architectural symbols in modern architecture is aroused wide attention. This article used the basic theory of semiotics, the significance of architectural symbols, the application and innovation of architectural symbols to discuss the significance of Chinese traditional architectural symbols. Then analysed the application and development of Chinese traditional symbols in order to make it revitalized in new buildings

For 1 and 2, as the substituents change from H to methyl, the dimensions of 1-2 decrease from three-dimension (3D) to one-dimension (ID) due to the steric effect of methyl groups. For 3 and 4, as the ratios of Ag2O/apyz/pma vary from 1:1:1 to 2:1:1. the structure of 3 is a 1D ladder structure built from Ag-apyz double chains and pma anions, while the structure of 4 is a two-dimension (2D) grid. As excess ammonia is added to above four reaction systems, the structure of 5 contains unprecedented {[Ag(NH3)(2)](+)}(n) chains and pma anions. The substituent on the pyrimidyl ring, ratios of reactants, solvent systems and ligand isomers intensively influence the coordination environments of metal ion and the coordination modes of the carboxyl group, and thus determine the structures of the coordination polymers. The photoluminescent properties of 1-5 were also investigated. (C) 2010 Elsevier Ltd. All rights reserved.National Natural Science Foundation of China 20721001 MSTC 2007CB81530

Both complexes have been characterized by element analysis, IR and single-crystal X-ray diffraction. The monodentate dmapym and tridentate mal ligands link Ag(I) ions to give complex 1 a one-dimensional (1D) H-shaped chain structure. The complex 2 is a two-dimensional (2D) double sheet structure constructed by (4,4) single sheet. Additionally, the hydrogen-bonding and C-H center dot center dot center dot pi interactions also direct the self-assembly of supramolecular architectures. The photoluminescence properties of the 1 and 2 were investigated in the solid state at room temperature. (C) 2010 Elsevier B.V.

重组人类T淋巴细胞白血病病毒抗原及双抗原夹心法ELISA抗体诊断试剂盒的研制

为研制灵敏、特异的抗人类T淋巴细胞白血病病毒(HTLV)抗体诊断试剂,将一段HTLV Ⅰ和HTLV Ⅱenv区嵌合基因在大肠杆菌中表达,获得的重组抗原具有良好活性。将该抗原作为酶标记抗原建立双抗原夹心法ELISA(dsELISA),对31份HTLV Ⅰ型血清和19份HTLV Ⅱ型血清均能100%检出,而在5065份各种阴性血清中特异度为99 94%。用dsELISA试剂与进口间接法试剂(GeneLabs试剂)平行检测18份HTLV Ⅰ参比血清、17份HTLV Ⅱ参比血清和1024份献血员血清,结果dsELISA试剂正确率为100%,对HTLV Ⅰ型血清和HTLV Ⅱ型血清的反应性基本相同,平均s/co值显著高于GeneLabs试剂。而GeneLabs试剂对HTLV Ⅱ型血清的反应性显著弱于Ⅰ型,并有2份BBI参比血清中的Ⅱ型血清漏检。另外,GeneLabs试剂在献血员血清中出现9例假阳性,特异性显著低于dsELISA试剂。这些结果表明:所研制的dsELISA试剂可用于HTLV Ⅰ型和Ⅱ型血清的检测,其灵敏度和特异度均优于进口间接法诊断试剂

Confronting the Middle Kingdom:The History of Tribute System Revisited through CHUN Hae-jong and LEE Choon-shik

若要談兩千多年的韓中關係史，就不可忽略朝貢關係。雖然有些韓國學者批評，朝貢關係只是在韓中關係中的一部分，但是在兩國關係的歷史裡，朝貢─冊封關係的重要性，是不可不注意的事實。由此可見，要了解韓中關係，必須先理解兩國的朝貢關係。 以費正清為代表的西方學者，以及中國大陸、香港、台灣等華人學者，雖然對朝貢體系的細節上有所不同，但是以中國為主的「中國中心主義」的基本觀念脈絡卻是大同小異。亦即，在東亞的朝貢體系，是以中國為中心來構成的國際秩序。學者譚中甚至否認朝貢體系的國際性，認為朝貢體系是中國與周邊地域之間的國內關係。事實上，以前述方式理解朝貢體系，很容易忽視周邊國家的視角。換言之，如果只強調基於中國為主的朝貢體系，便無法得知東亞國家參與朝貢體系的動機。 日本學者濱下武志雖然同意從以中國為中心的觀念為起始，但是他超越前述理論，提出「亞洲經濟圈」，以亞洲的歷史，將朝貢體系看成國家之間的經濟貿易關係，以中國近代經濟史地的視角，挑戰「西方中心論」。誠然朝貢體系具有經濟面相，但濱下僅強調朝貢體系的經濟面，忽略政治、軍事、文化等複雜的面相。 韓國學者的看法，則與中、西學者以及濱下武志的看法不同。全海宗把朝鮮與明、清朝的朝貢關係設定典型朝貢關係，從朝鮮的立場出發，檢討兩千多年的朝貢關係史。李春植則認為朝貢體系不是中國的專有物，透過古代中國朝貢體系他指出朝貢體系的泛東亞外交關係。目前對朝貢體系，像鄭容和、Yun Peter的韓國學者進一步主張，除了明、清時期，韓國接受以中國為主的朝貢關係，在其他時期並非主從關係，至少早期的韓中朝貢關係是以現實考量出發的對等關係。 本文透過全海宗與李春植的研究，闡發韓國立場詮釋下的朝貢體系，介紹全海宗所理解的韓中朝貢關係，以及試圖超越中國中心概念下的朝貢體系，並論及其他韓國學者對於韓中朝貢體系的研究，重新檢討韓中朝貢關係，以及韓中朝貢關係的意義。The tributary system has taken an important position in the past Sino-Korean Relations that goes back to almost 2000 years ago. Although some Korean scholars insist that the system has merely taken a partial role in the whole Sino-Korean Relations, the importance of understanding the true nature of the tributary system is in no way negligible. Without it, we cannot analyze Sino-Korean relations in depth. Many scholars have maintained the perspective that puts an emphasis on “sinicization.” Such scholars include Western scholars like Fairbank J. K as well as Chinese scholars from mainland China, Hong-Kong, and Taiwan. Despite some minor differences, they hold the common view that the tributary system means a Sino-Centric international order in East Asia. Tanchong even insists that the tributary system is a domestic order between China and her neighboring regions. The loophole in such perspective is to overlook how the tributary system has been viewed from the neighboring states; for example, the real motives why these state chose to participate in the tributary system have been hardly discussed. HAMASHITA Takeshi, a Japanese scholar, transcends from the Sino-Centric notion and discusses the tributary system as “Asian economic bloc.” By regarding the tributary system as economic trade relations in East Asia, he challenges the view of ‘Occidental-Centric’ view. However, in reality, the tributary system is not just about economic relations. Besides economic aspect, a balanced discussion of the tributary system should put into consideration political, military, and cultural aspects of the system as well. Korean scholars’ view differs from Chinese, Western, and Japanese scholars. CHUN Hae-jong defines the relations between Chosun and Ming, Qing as “typical Tributary relations.” From the standpoint of Chosun, he has studied the past Sino-Korean Tribu tary System. LEE Choon-shik, through studying the Tributary System in ancient times , insists that the Tributary System was not monopolized by China, but actually formed general diplomatic relations in the Pan-East Asian regions. Recent works by Korean scholars reflect more progressive considerations about Sino-Korean Tributary System; early Sino-Korean relations in the Tributary System (prior to Ming, Qing dynasty)was rather reciprocal relations based on realism. This thesis has studied how Korean scholars such as CHUN Hae-jong and LEE Choon-shik have analyzed the tributary system. Their works show the interpretation of the tributary system from the stance of Korea, and offer an alternative perspective that departs from the sino-centric view of the tributary system. This contributes to our balanced understanding of the Sino-Korean tributary relations in the past

code execution security mechanism for open cloud & client computing

云端计算可以充分聚合Internet网络服务器端和边缘终端节点的计算资源来获得更大的效益.但将计算任务部署到用户终端上执行却带来了安全隐患.分属于不同用户的海量终端节点之行为显然不可靠,计算安全性也难以保障.特别是作为任务执行者的用户终端节点可能篡改任务中的程序代码或数据,返回的是虚假的结果,或是窥探有私密性要求的代码和数据.提出一种新的基于内嵌验证码的加密函数的代码保护机制,它可同时满足计算完整性和私密性,能够有效验证返回结果的正确性,并保障计算代码不被窥知.为了进一步提高任务执行的成功率和缩短作业周转时间,将任务代码优先分发给信誉良好且执行成功率高的节点来执行.还提出了一种评估任务执行节点可信性的方法.具体描述了任务执行代码保护机制的实现流程,并对机制的性能进行了详细的分析与验证.国家自然科学基金项目(60873231)|国家教育部高等学校博士学科点专项科研基金课题(20093223120001)|中国博士后科学基金项目(2011M500095)|江苏省科技支撑计划(BE2009158)|江苏省自然科学基金(BK2011754,BK2009426)|信息安全国家重点实验室开放课题(03-01-1)|江苏省高校自然科学研究项目(09KJB520010)|江苏高校优势学科建设工程项目(yx002001)资
