2004日本花博会主入口

主入口设计提案意在将其营造成一种竹林环境。设计者意图创造一个内外界限模糊的空间,使其成为一个区域并拥有一定的厚度,而不是清晰地划分界限。更确切地说,是挂着的2328条竹片,形成了一种竹林氛围,这个竹林被当作"大门"。竹林的周边则由不昂贵但高透明的格扇网柔和地包裹着。     

安养寺木造阿弥陀如来坐像收藏设施

该项目是要为安养寺木造阿弥陀如来坐像(作为重要的文化财产)建一个收藏地。这尊坐像从12世纪开始就坐落在山口县丰浦郡的安养寺。外墙由35cm厚土砖砌成,采用当地传统土砖工艺。部分墙面用钢板加固,土砖设计成多孔状,以过滤空气和光线。因为土砖有湿度控制功能,所以室内不需要安装空调,可以利用材料自行调节环境。     

莲屋

这是一座深山之中，依河而栖的房子。设计者想在房子与河流之间，用水注满，植莲其中，将居处托向河面，直达彼岸的林翳。 建筑的本身，则可径直看做是孔洞的组合。分开的两翼中夹着洞状的露台，从而将房后的树林同对岸的树林连接起来。墙体的表层也设计成了无数的孔洞。     

织部茶室

这是一个临时的、可移动的茶室。波纹状的5mm厚的塑料板以65mm间隔排列并且用长形绳索捆扎固定。一旦绳索被松开,茶室就被还原成一堆便宜的组件,进而方便移动迁移。整个设计概念来自于一个形状不规则的蚕茧,是对古田织部所设计的不规则茶碗的致敬。     

Characterization of a class III chitinase from Vitis vinifera cv. Koshu

A chitinase gene (Chi3K) was cloned from the genomic DNA of Vitis vinifera cv. Koshu. The structural gene comprised 891 by without introns and encoded 297 amino acids. The Chi3K product showed high similarity to the class III chitinase of V. vinifera cv. Pinot noir. Chi3K was expressed using a bacterial expression vector for purification and enzymatic characterization of its gene product. The recombinant chitinase exhibited hydrolytic activity toward glycol chitin and its optimum pH was 4.0. It also inhibited the growth of Botrytis cinerea, which causes grey mold disease in grapes.     

Experimental TCP Performance Evaluation on Diffserv AF PHBs over ATM SBR Service

In these days, IP network customers become sensitive to the QoS guarantee provided by the network. Amongst many QoS guarantee schemes, Diffserv (Differentiated Services) is the one of the most practical candidates for the next generation IP networks. Under these circumstances, the commercial network venders have already provided the Diffserv routers that support EF (Expedited Forwarding) PHB (Per Hop Behavior). However, AF (Assured Forwarding) PHB in Diffserv still has not been provided by commercial routers. Therefore, it is a realistic solution that SBR3 (Statistical Bit Rate 3) of ATM emulates AF PHB, but it is not clear whether TCP traffic over AF PHB emulated by ATM is differentiated from the best effort TCP traffic over DF (Default Forwarding) PHB. To confirm the differentiation, we have experimentally studied TCP performance through the link into which TCP connections over AF PHB and DF PHB are aggregated. This paper describes the experimental results and discusses the possibility of the TCP performance differentiation between AF PHB and DF PHB over ATM.     

Locating congested segments over the Internet by clustering the delay performance of multiple paths

Delay variation-based detection and location of congestion in a large network is considered. Since the Internet is still highly prone to performance deterioration due to transient large delays, locating a part of the network (segments) responsible is vital to ensure that Internet Service Providers can mitigate or prevent such performance deterioration. In the proposed method, the end-to-end packet delays from multiple origins to multiple destinations are actively and continuously measured. By analyzing those data on delay variation along each monitored path, congestion is detected by finding a delay performance deterioration worse than a predefined criteria and a congested segment responsible could be inferred by finding a set of paths among which delay variations are strongly correlated. This is a network tomographic approach based on a clustering technique that effectively tackles the correlation among packet delay variation along individual paths. The proposed method was evaluated through a real-world long-term experiment on the Japan’s commercial Internet, and was shown to have considerable potential to promptly locate congested segments through various analyses on the experimental results.     

育龄妇女非意愿妊娠原因分析与对策研究

采取整群抽样调查方法,对2011年1月—2013年5月在秭归县、夷陵区计划生育服务站因非意愿妊娠而实行人工终止妊娠对象,通过查阅病历资料和调查问卷,了解非意愿性妊娠原因及相关因素。1 360例非意愿妊娠中,未婚为21.62%,已婚为78.38%;人群分布在20~39年龄段(73.82%);孕次分布主要在孕2~孕3的对象为57.87%;非意愿妊娠中避孕措施失败者为44.34%,无措施者为55.66%。避孕措施因素宫内节育器为10.51%,避孕套为10.51%,避孕药为8.24%,外用为6.62%,其他为8.46%。存在侥幸心理和取出宫内节育器(IUD)后续措施没能跟进是无措施者导致非意愿妊娠的主要原因。避孕知识知晓率为98.90%,对紧急避孕的知晓率仅为15.37%,知道哺乳期需避孕者为18.38%。医务人员、计生干部、宣传资料是已婚人群获取避孕知识的主要途径,农民及农民工对象获取免费服务高于城镇居民、国家工作人员、商业服务人员及外来流入人员。
