Successive Earthquake-Tsunami Analysis to Develop Collapse Fragilities

Over the last half century, scientists and engineers have developed methods to better understand and mitigate the damage caused by tsunamis. According to U.S. Federal Emergency Management Agency (FEMA) P646, buildings in many regions, including the U.S. Pacific Northwest, will experience substantial ground shaking from an offshore earthquake that precedes a tsunami and then experience the tsunami forces themselves. Thus, both hazards should be considered in computing the damage and collapse risk to buildings. This article summarizes a basic approach to numerically consider the successive seismic and tsunami risk to buildings in near-field tsunami regions such as the U.S. Pacific Northwest.     

Full-Scale Experimental Verification of Soft-Story-Only Retrofits of Wood-Frame Buildings using Hybrid Testing

The FEMA P-807 Guidelines were developed for retrofitting soft-story wood-frame buildings based on existing data, and the method had not been verified through full-scale experimental testing. This article presents two different retrofit designs based directly on the FEMA P-807 Guidelines that were examined at several different seismic intensity levels. The effects of the retrofits on damage to the upper stories were investigated. The results from the hybrid testing verify that designs following the FEMA P-807 Guidelines meet specified performance levels and appear to successfully prevent collapse at significantly higher seismic intensity levels well beyond for which they were designed. Based on the test results presented in this article, it is recommended that the soft-story-only retrofit procedure can be followed when financial or other constraints limit the retrofit from bringing the soft-story building up to current code or applying performance-based procedures.     

The Takarazuka Girls’ Revue in the West: public–private relations in the cultural diplomacy of wartime Japan

This essay examines wartime Japan’s establishment of culture bureaus and its promotion of the Takarazuka Girls’ Revue in allied European nations and the United States in a moment of international crisis. This overseas cultural policy was part of a series of alternative strategies employed by the Japanese Ministry of Foreign Affairs in an effort to persuade the West to acknowledge Japan’s self‐appointed role as a leader in East Asia, capable of producing advanced cultural products on a par with those of western nations. Key features of this essay include the negotiation between state goals and private interests in the performance of cultural diplomacy, as well as the aesthetic articulation of a hybrid Japanese culture which was traditional yet fully modern, particularly as presented on stage through a display of the female body.     

Democratization and museum policy in South Korea

ABSTRACT

This article examines the two distinct historical policy paths taken by the South Korean government in the late twentieth century towards the democratization of museums. One was based on the creation of a museological public sphere as an extension of the political democratization movement of the 1980s. This demonstrated the potential to become a valuable component of the wider incipient national public sphere within which civic subjects could discuss their individual and collective historical memories. However, despite this potential, a museological public sphere failed to influence the general trajectory of national policy regarding the democratization of museums that had been in development since the early 1980s. This other policy path towards cultural democratization was triggered by the award of the Seoul Olympics in 1981. It was based on public participation and entitled the ‘cultural Olympics’. An important strategy of the cultural Olympics was the construction of a new institutional infrastructure to expand the public right to enjoy culture. This path facilitated an increasing entanglement with neoliberalism in 1990s. Finally, the 1997 IMF crisis furthered the association between a superficial idea of democratization through institutional expansion and the practices of neoliberalism, a trend which continues within South Korean museum policy today.     

Amplification and sequencing of Trichuris trichiura ancient DNA extracted from archaeological sediments

Despite high prevalence of Trichuris trichiura infection, PCR-based analysis on T. trichiura from archaeological samples has not been established so far. In the present study, we sought to perform PCR-based amplification of T. trichiura aDNA using the sediments from medieval tomb of Korea. The presence of Trichuris eggs were first detected by microscopic observation; then confirmed by PCR-based aDNA analysis. Obtained sequence showed 100% homology to that of the small subunit ribosomal RNA (SSUrRNA) gene of T. trichiura but distinct from that of other Trichuris species. PCR-based aDNA analysis in this study can serve as effective method to confirm the presence of T. trichiura eggs in the soils or coprolites collected from archaeological sites.     

唐代“六胡州”州城的建置及其运用——“降户”的安置和役使的一个类型

唐朝在突厥降户中贾胡的处理上采取把他们安置在适合生活的地方,并对之进行驱使的办法。这典型的表现在"六胡州"州城的建置及其运用之上。六胡州设于"河曲"之地的中西部一带,介于六州中的灵州、夏州之间,是指鲁、丽、塞、含、依、契等六小州。在突厥降户中,主要是贾胡降户被集体安置在这些州城之内。这些州城位于今内蒙古自治区河套地区的最南段一带,以及长城以北较为狭窄的地区,属于北方著名的湖泽地区,利于养马。六胡州民之所以主要由贾胡降户来组成,是因为他们具有养马等技术特长。他们在六胡州的州城内受到统治,并受驱使从事养马的工作。六胡州在高宗调露元年建置,这时唐朝正好遭遇养马大量丧失的危机,这是建置六胡州的重要原因。此外,六胡州因"以唐人为刺史",而不称羁縻州。六胡州民居于州城内的"坊"里。他们不一定都一直活动在州城之内,但应"编籍"在州城中一定区域的名称之下。     

Germs, hosts, and the origin of Frank Macfarlane Burnet's concept of "self " and "tolerance," 1936-1949

In the early twentieth century, the living organism's ability to distinguish its "self" from foreign entities such as bacteria, viruses, transplanted tissue, or transfused blood was a major problem in medical science. This article discusses how the Australian immunologist Frank Macfarlane Burnet arrived at a satisfactory explanation of this problem through his 1949 theory of "self" and "tolerance." Burnet's theoretical work began from his study of diverse factors affecting the conditions of the host and the germ for the occurrence of infectious diseases. Among them, the host's age came to receive his attention as a crucial factor. This understanding was facilitated by his acceptance of cytoplasm inheritance theories, which emphasized the importance of the embryonic host's changing conditions according to its age. Based on this idea, he claimed in 1949 that the "self" of the organism was defined during its embryogenesis. Peter B. Medawar and his colleagues' demonstration of Burnet's claim became the basis for awarding Burnet and Medawar the Nobel Prize in Physiology and Medicine in 1960. While previous histories have focused on Burnet's "inductive reasoning" or "ecological perspective" to explain his conception of the theory of "self" and "tolerance," this article finds the origin of his ideas within an important line of modern medical research engendered through the development of germ theories--the studies of the host body and its relationship with parasites.     

中国科技园区位布局探析--以西安科技园区为例

科技园区是20世纪高技术产业化方面最重要的创举,创建科技园区以发展高技术产业已成为国际趋势。国内外研究表明,科技园区成功的关键的因素之一是区位布局,一般只有大城市的区位条件,才能为高技术企业的技术创新提供各种聚集经济条件。因而科技园区必然在城市化地区首先出现。但国内外科技园区的实践证明,这一结论没有普遍性。本分析了科技园区布局的一般规律,并以西安科技园区位布局为例作分析验证,以期为科技园区的布局提供科学依据。
