1 Results In order to obtain liquid crystals including an ion atom as a transition metal, the ferrocene derivatives containing mesogenic group were designed with a view to prevent great bulk of ferrocenyl moiety in the molecules, because rod-like molecular shape is preferable to show liquid crystallinity. Therefore, methylene chain was installed as a flexible spacer between ferocenyl moiety and mesogenic one. As a result, a lot of liquid crystalline ferrocene derivatives were synthesized successfully.

The maximum beam current that can be accelerated in an energy recovery linac （ERL） can be severely limited by the transverse multi-pass beam breakup instability （BBU）, especially in future ERL light sources with multi-GeV high energy beam energy and more than 100 mA average current. In this paper, the multi-pass BBU of such a high energy ERL is studied based on the simulation of a 3-GeV ERL light source that is proposed by KEK. This work is expected to provide a reference for future high energy ERL projects.

The energy of tagged photons, which were provided from the internal photon tagging system of the Laboratory of nuclear Science, Tohoku University, has been calibrated using the d（γ,π-pp） reaction. Charged pions and protons in the final state were detected with the neutral Kaon Spectrometer （nKS2）. Photon energies were obtained from the reaction of d（γ,π-pp）. The derived photon energy was consistent with the design of the tagger system and the previous measurement using electron-positron pair production. The consistency demonstrates the performance of nKS2 and the capability of the photon energy calibration using d（γ,π-pp）.

The reactions γd→π-pp and γd→npπ+π-have been studied in an energy range from 0.8 to 1.1 GeV at the tagged photon facility of Laboratory of nuclear Science,Tohoku University. Charged pions and protons in the final state were measured by using the neutral Kaon Spectrometer (nKS2). The analysis of the γd→π-pp was mainly used to check the acceptance of the nKS2 and to calibrate the tagged photon energy. The photoproduction of the Δ++Δ-was identified in the γd→npπ+π-reaction. Since the data analyses are still in progress,we issue an interim report and preliminary results.

We are now preparing for the third generation (e,e' K+) Λ hypernuclear spectroscopic experiment at Hall C,Jefferson Lab (USA). The goal of the experiment is the precise spectroscopy of hypernuclei in wide mass region. We have constructed a new high resolution electron spectrometer "HES" dedicated to (e,e' K+) hypernuclear study in Japan and it was shipped to JLab in February,2008. We will discuss about the physics of the (e,e' K+) hypernuclear study at JLab and report the current preparation status of the third generatrion experiment.

传统的成人原位肝移植手术需使用常用的静脉静脉血管旁路的腔静脉重建技术。近年来无血管旁路转流的背驮式技术已开始广泛应用。该研究的目的是评估成人原位肝移植手术常规运用背驮式技术的效果。美国迈阿密大学Jackson Memorial医学中心对1994年6月到2001年7月完成的成人原位肝移植1067例进行回顾性分析，对病人的人种、影响因子包括冷缺血时间、热缺血时间、手术时间、输液量、出血量、以及手术后结果进行评估。结果显示，共有918例进行背驮式肝移植，运用背驮式肝移植技术可减少输血量、热缺血时间、以及减少使用静脉-静脉旁路转流。运用背驮式肝移植技术的病人有75例（8．3％）出现顽固性腹水，5例（0．54％）静脉流出道狭窄（P=nS），术后肝肾功能衰竭发病率与传统手术相似。背驮式肝移植的总的1、3、5年存活率分别为85％、78％、72％。单一变量分析提示：腔静脉重建方法、冷缺血时间、热缺血时间、总输液量、总住院日、供肝年龄、以及肝脏肿瘤表现是影响移植肝存活的显著因素；多变量因素分析提示：冷缺血时间、供肝年龄、总输液量、以及总住院日是移植肝存活的预后因素。作者认为，大部分的成人原位肝移植可运用背驮式技术。
