A novel method has been established to realize the experiment of electron scattering off short-lived nuclei. the method was based on the well known ＂ion trapping＂ phenomenon in electron storage rings. In the R^D experiments at Kyoto University, stable nucleus, 133^Cs, was employed as the target nucleus. the luminosity of scattering experiment was nearly 1026 cm^-2s^-1 at electron beam current around 75 mA. the angular distribution of elastically scattered electrons from trapped Cs ions was measured and the result was well fitted by theoretical calculation. It was indicated that higher luminosity can be reached with larger electron beam current.

AIM:to delineate indications and limitations for "ex tended" radical cholecystectomy for gallbladder cancer:a procedure which was instituted in our department in 1982. MEtHODS:Of 145 patients who underwent a radi cal resection for gallbladder cancer from 1982 through 2006, 52 (36%) had an extended radical cholecystec tomy, which involved en bloc resection of the gallblad der, gallbladder fossa, extrahepatic bile duct, and the regional lymph nodes (first-and second-echelon node groups). A retrospective analysis of the 52 patients was conducted including at least 5 years of follow up. Residual tumor status was judged as no residual tumor (R0) or microscopic/macroscopic residual tumor (R1 2). athological findings were documented according tothe American Joint Committee on Cancer Cancer Stag ing anual (7th edition). RESULtS:he primary t mor as classified as patho-logical t1 (pt1) in 3 patients, pt2 in 36, pt3 in 12, and pt4 in 1. twenty three patients had lymph node metastases; 11 had a single positive node, 4 had two positive nodes, and 8 had three or more positive nodes. None of the three patients with pt1 tumors had nodal disease, whereas 23 of 49 (47%) with pt2 or more advanced tumors had nodal disease. One patient died during the hospital stay for definitive resection, giv ing an in hospital mortality rate of 2%. Overall survival (OS) after extended radical cholecystectomy was 65% at 5 years and 53% at 10 years in all 52 patients. OS differed according to the p classification ( the nodal status ( = 0.010). All of 3 patients with pt1 tumors and most (29 of 36) patients with pt2 tu mors survived for more than 5 years. Of 12 patients with pt3 tumors, 8 who had an R1 2 resection, distant metastasis, or extensive extrahepatic organ involve ment died soon after resection. Of the remaining four pt3 patients who had localized hepatic spread through the gallbladder fossa and underwent an R0 resection, 2 survived for more than 5 years and another survived for 4

this paper presents the recent progress in our project of estimating near real-time electric fields and currents in the ionosphere through our computer system called the Geospace Environment Data Analysis System (GEDAS). We show a new technique in which data from ground magnetometers are collected by the system and used as input for the KRM and AMIE programs to calculate the distribution of ionospheric electric fields and currents, as well as of other ionospheric parameters, such as electric potential patterns. One of the goals of this project is to specify ionospheric processes. Examples of the near real-time calculation and the data flow of our scheme are presented.

Background: the promotion of family nursing by public health nurses (PHN) presupposes an accurate assessment of the family nursing support they already provide. However, as there is no assessment tool for this purpose, this study aimed to develop a scale to assess family nursing currently provided by PHN. Methods: We developed the Family Nursing Practice Scale (FNPS) for PHN based on the results of a previous study. the content validity of the FNPS was established through discussion with three other researchers. A pilot study was conducted to confirm face validity. to confirm reliability and validity, an anonymous, self-reported questionnaire was sent to PHN working in municipal offices. the statistical analyses included the Kaiser-Meyer-Olkin (KMO), Barlett’s test of Sphericity, exploratory factor analysis (EFA), Cronbach’s alpha, correlation coefficient and t-test. Results: Seven hundred fifty-four PHN participated in this study. Cronbach’s alpha of FNPS was 0.94. the KMO measure was 0.948, and Bartlett’s test of Sphericity was p two factors together accounted for 63.2% of the variance in EFA. No items were excluded because of low loadings. Construct validity was confirmed through comparison with categories from a previous study. the correlation coefficient of FNPS and selected items of the Practice of Breastfeeding Support Scale was r = 0.56 (p the result of the t-test showed that the FNPS score of PNH who had received training in family nursing was significantly higher than that of PHN who had not (t = -2.0;p the reliability and validity of the FNPS were confirmed. the FNPS comprised 15 items and two factors. the score for “Active support for the family” was lower than “Support given with awareness of the family’s situation.” the findings of this study strongly suggested that the FNPS would be effective in clarifying the current state of family nursing provided by PHN and factors related to this activity and thus greatly ass
