I am grateful to the Society for the opportunity to mark the centenary of the Enabling Act and the beginning of the Church Assembly with some reflection on an often ignored but highly valuable feature of that inauguration: the Single Transferable Vote or STV. I tried on one respected registrar recently an illustration of what the task must be like for those who do not welcome it. Was it, I suggested, like a blind person doing a jigsaw where the pieces were all shaped differently from each other – in other words, where the blind person could ensure that it was put together accurately, but on the other hand never saw the picture? The response was that that picture reflected accurately how it had in fact felt to that registrar. That might suggest that this lecture should be explaining and commending STV as general good practice, but in the event the process and virtues of STV have here to be largely taken for granted. I offer here one short commendation of STV.

This article presents a method for designing a planar guide device that can guide sliders to move along a straight-curved rail and can eliminate the backlash between the slider and the rail throughout the whole range of the slider travel. The guide device has many sliders and each slider has three rollers that can separately roll on both sides of the rail. The straight-curved rail is composed of straight sections, connection sections, and circular-arc sections. For each slider, the three normal lines through the contact points between the rollers and the rail must always intersect at a common point, which is an instant center. Using this as a basis, the side profiles of the straight-curved rail can be determined. To avoid infinite jerk of the slider motion, the pitch curve of the connection section should consist of a transition curve, which is interposed between the straight line and the circular arc.

Abstract Background: Accurate placement of cannulated screws is the key to stable fixation of the femoral neck fracture. A novel device was developed to improve the accuracy of screw placement.Methods: 20 synthetic femoral bones were divided into conventional technique group and the experimental group. Three Kirschner wire were inserted into the femoral neck fracture by conventional technique or by the simple guide device. The operative time, total drilling times and fluoroscopic frequency were evaluated.Results: By using the guide device, the fluoroscopy and operation time of the experimental group were shorter that of the conventional method. The total drilling times with the simple guide device were significantly lower than the conventional technique group.Conclusions: This device can help trauma surgeons shorten the surgical time and reduce radiation exposure time. The use of this guide device can make screw fixation for femoral neck fracture easier.

Normal Work

□ Rather than being prevented from becoming involved in so-called normal work activities, blind persons should be encouraged to explore, evaluate, and expose themselves to a much broader variety of work experiences. In this way, the blind person will be much better equipped to select a vocational goal more easily as well as more realistically. Early concentration on the development of personal skills and occupational knowledge should be initiated and supported by the vocational consultant. The responsibility then is to work toward altering the emphasis in work for the blind from one of inability to perform competitively to one of almost limitless potential. Only such positive concepts can help to turn the tide for the blind worker and result in the prevention of vocational disabilities.

ABSTRACT Objective: The aim of this study is to assess the surface roughness of the implant-retained mandibular bar overdenture (BOD) and the implant-retained mandibular ball joint overdenture (BJOD) in jaw and its relation with the adhesion of molds and yeasts and mesophyll aerobe, in time 30 and 180 days in mouth. Materials and Methods: Five-systems titanium bar CARES® and synOcta® Straumann® Dental Implant System, Holding AG Inc., Basel, Switzerland (BOD), and five-systems joint ball Klockner® Implant System; Soadco Inc., Escaldes-Engordany; Andorra (BJOD), were used in two parallel groups of five participants, in an essay to simple blind person. To 30 and 180 days, the overdentures were withdrawn and evaluated the Ra: ųm. SJ-301® Mitutoyo Corporation Inc., Kanagawa, Japan, and the adhesion of microorganisms (colony-forming unit/ml). Results: The results were as follows: the Ra: Um (30th and 180th): BOD, 0.965–1.351; BJOD, 1.325–2.384. Adhesion: Molds and yeasts, BOD, 2.6 × 102 and 4.6 × 103; BJOD, 3.0 × 102 and 5.3 × 104. Adhesion: Mesophyll aerobe, BOD, 3.8 × 106 and 5.8 × 106; BJOD, 4.3 × 106 and 7.1 × 107. Conclusions: At 30 days (P = 0.489), there were no differences in BOD and BJOD for adhesion of molds and yeasts and mesophyll aerobe between both overdentures. At 180 days (P = 0.723), there were differences in the adhesion of mold and yeast and mesophyll aerobe, being greater in BJOD.
