Georadar investigations in the central nave of Hagia Sofia,Istanbul (Turkey)

Within an interdisciplinary project to study Istanbul’s Hagia Sofia, a georadar survey was carried out in the central nave to assess if the deformations of the structure previously observed could be related to a differential behavior of the subsoil caused by architectural remains underneath. This study faces an unusual challenge since it was necessary to study the space beneath the scaffolding placed for the restoration works. The survey of the central nave was successful and allowed the detection of remains of walls that probably formed the basement of a previous 18- by 22-m structure. In addition, another interesting feature was discovered 2 m below the marble mosaic in the southeastern part of the nave. Although it is not possible to define its function, it seems that there could be a close relationship between this 2- by 3-m buried structure and the marble mosaic in the floor surface. Although some structures were identified under the floor of Hagia Sofia, there are no major changes in the topography of the central nave floor.     

Lithic technology and social transformations in the South Indian Neolithic: The evidence from Sanganakallu–Kupgal

Here we examine patterns in stone tool technology among Mesolithic, Neolithic and Iron Age localities in the Sanganakallu–Kupgal site complex, Bellary District, Karnataka, South India. Statistical tests are used to compare proportions of raw materials and artefact types, and to compare central tendencies in metric variables taken on flakes and tools. Lithic-related findings support the inference of at least two distinct technological and economic groups at Sanganakallu–Kupgal, a microlith-focused foraging society on the one hand, and on the other, an agricultural society whose lithic technologies centred upon the production of pressure bladelets and dolerite edge-ground axes. Evidence for continuity in lithic technological processes through time may reflect indigenous processes of development, and a degree of continuity from the Mesolithic through to the Neolithic period. Lithic production appears to have become a specialised and spatially segregated activity by the terminal Neolithic and early Iron Age, supporting suggestions for the emergence of an increasingly complex economy and political hierarchy.     

Experimental examination of animal trampling effects on artifact movement in dry and water saturated substrates: a test case from South India

This paper presents the motivation, procedures, and results of an experiment that examines short episodes of animal trampling in dry and water saturated substrates in South India. While horizontal artifact displacement was similar to that modeled by other trampling experiments, vertical artifact displacement in water saturated substrates was greater than any reported experiment to date. The toolstone used in this experiment, a silicious limestone, exhibited minimal damage after trampling. Artifact inclination patterning appeared to be a potentially diagnostic middle-range marker of trampling in water saturated substrates. Given the abundant number of Paleolithic sites that are located on flat, open surfaces near water-bodies, or experience monsoonal climatic regimes, we propose that future excavations should measure artifact inclination on a regular basis.     

韩国粉青沙器的白化妆土工艺及其与中国陶瓷的关系

本文的主题是研究粉青沙器的化妆土工艺出现的历史背景,旨在探讨中韩陶瓷交流对粉青沙器制作的影响。在韩国陶瓷历史上,朝鲜时期(1392-1896)的粉青沙器是具有独特工艺特征的陶瓷样式,即在胎上用白化妆土粉妆,然后采用多样装饰技法,和磁州窑瓷器相似。关于朝鲜王朝制瓷业开始使用化妆土装饰技法的突然性和白瓷生产需求的背景,作者从中韩陶瓷交流史的角度,提出了两个论点:首先,高丽(918-1392)末朝鲜初期制瓷业衰退,在原料和工艺技术恶劣化的情况下,通过借鉴高丽时期已传入的中国磁州窑瓷器的化妆土工艺;应用于粉青沙器的生产。其次,中国陶瓷文化由青瓷转移到白地花纹的青花瓷器的发展趋势,直接影响到朝鲜制瓷业追求白瓷或白地瓷的状况,而在当时朝鲜制瓷业条件的限制下,只能以化妆土工艺表现白色地。这一现象也反映了当时中国先进陶瓷文化及陶瓷审美观念的变化。     

韩国的当代中国政治研究述评

迄今为止,还没有对韩国的中国政治研究状况做出评估。韩国的当代中国政治研究值得关注至少有以下三个理由:第一,韩中关系在过去十多年取得了非同寻常的扩展;第二,在中国学习的外国学生中,韩国留学生的数量最多;第三,尽管刚刚起步,越来越多的韩国学者在当代中国研究的主流英文期刊如《中国季刊》(The China Quarterly)和《中国杂志》(The China Journal)上发表文章。本文主要对三类学术成果进行     

Agricultural illustrations of 19th century Korea: 'Imwon gyeongjeji' (Treatises on Management of Forest and Garden) by Seo Yugu

The generative relationship between text and image has long been established. Its structure evolved historically as a result of varying understandings of the functions of art and technology. Agriculture illustration, which emerged in China during the Song dynasty, is a prime example of this creative dialogue in which aspects of both disciplines were combined. Political, technological, and aesthetic concerns informed the reformulations of this new genre. This paper will address agricultural illustrations on nineteenth-century Korea, when notable changes occurred in the visualization of agricultural texts. It will explore changes in the understanding of the roles of agriculture, technology, and labor through an analysis of shifts in modes of illustration and the texts selected. The relationship between technology and visual representations during late Joseon Korea will be contextualized through an exploration of the evolution of technical drawing in East Asia. This paper will suggest that the recognition of imagery's ability to convey textual and technical information provided an important alternative paradigm for the presentation and use of knowledge.     

New compositional data on ancient mortars from Hagia Sophia (Istanbul,Turkey)

This study shows the results of a multidisciplinary collaboration between the University of Calabria (Italy) and the National Autonomous University of Mexico (UNAM), about the compositional characterization of some mortars taken from Hagia Sophia in Istanbul (Turkey), one of the most important buildings in antiquity. Twenty samples of joint mortars were analysed by micro-chemical analyses (SEM-EDS), X-ray powder diffraction (XRPD), optical microscopy (OM) and transmission electron microscopy (TEM). The compositional study allowed us to define, with more detail, the construction phases of the fifth, sixth and tenth century. The petrographic analysis in thin section by optical microscopy showed four typologies of sands, used as aggregate, with specific compositional features. SEM-EDS analyses and TEM observations of the binder around the ceramic fragments of the aggregate showed the presence of different morphologies of single C-S-H compounds.
