BackgroundHigh-fidelity simulation represents a primary tool in nursing education, especially when hands-on practical training is involved.ObjectiveWe sought to determine the influence of high-fidelity clinical simulation, applied during cardiopulmonary resuscitation (CPR) training, on blood pressure, heart rate, stress, and anxiety levels in 2 groups of nursing students. One group had experience in health contexts, whereas the other group had none.MethodsWe performed a quasi-experimental study. Data were collected between May and June 2015 and included measurements of all the resting values, before and after participation in CPR clinical simulations regarding the 2 groups of university students (ie, with and without experience).ResultsAn increase in vital signs was observed in students after participating in a clinical simulation scenario, especially the heart rate. In all students, increased stress and anxiety levels were observed before the first simulation case scenario. Also, in all study groups, a decrease in vital signs, stress levels, and anxiety was observed throughout the study.ConclusionsParticipation in high-fidelity simulation experiences has both physiological and psychological effects on students.

The article examines basic problems of the current system of government statistics from the perspective of business as a consumer of statistical data. Alternative possibilities for providing information on consumer markets and sectoral dynamics are discussed. Suggestions are made for improving the system of government statistics.

The Hebrew Bible should be taught like a foreign language in Israel too, argues Ghil‘ad Zuckermann, inter alia endorsing Avraham Ahuvia’s recently-launched translation of the Old Testament into what Zuckermann calls high-register ‘Israeli’. According to Zuckermann, Tanakh RAM fulfills the mission of ‘red ’el ha‘am’ not only in its Hebrew meaning (Go down to the people) but also – more importantly – in its Yiddish meaning (‘red’ meaning ‘speak!’, as opposed to its colorful communist sense). Ahuvia’s translation is most useful and dignified. Given its high register, however, Zuckermann predicts that the future promises consequent translations into more colloquial forms of Israeli, a beautifully multi-layered and intricately multi-sourced language, of which to be proud.

A mancha de mirotécio causada por Myrothecium roridum Tode ex Fr. foi observada em lavouras de algodão no sul do Maranhão, causando reduções de produtividade de até 60%. Os sintomas da doença são lesões necróticas, circulares, com estruturas salientes, os esporodóquios, de distribuição irregular. Foram observadas lesões nos pecíolos, brácteas, folhas e maçãs de algodoeiro cv. Deltapine Acala 90, Fibermax 966 e Sure Grow 821. O isolamento do fungo foi realizado em meio de cultura batata-dextrose-ágar (BDA). O teste de patogenicidade foi realizado em maçãs sadias, destacadas de algodoeiro cv. Fibermax 966, no estádio vegetativo R6, previamente desinfestadas. Foram testados 13 isolados de M. roridum, oito provenientes de algodão e cinco de soja. Avaliações das estruturas fúngicas foram realizadas com auxílio de microscópio óptico equipado com um micrômetro ocular. Os isolados causaram infecções em maçãs de algodão e destacou-se como mais agressivo o MA-75, proveniente de algodão, apresentando diâmetro médio de lesão de 1,3cm, aos sete DAI e 2,7cm aos 14 DAI. Todos os isolados formaram esporodóquios dispostos concenticamente em meio BDA. Os conídios são unicelulares, hialinos a oliváceos, abundantemente produzidos em massa verde-oliva a preta. Os conídios de isolados provenientes de algodão mediram, em média, 5,1µm x 1,5µm, e os obtidos de soja, 5,8µm x 1,5µm. Estes resultados relatam a ocorrência da mancha de mirotécio, causada por M. roridum, em lavouras comerciais de algodão no Brasil.

Tissue polypeptide antigen (TPA) has been detected by immunocytochemical assay on urine cytological samples from 28 asymptomatic patients, who previously had a histological diagnosis of papillary transitional cell carcinoma (PTCT) of the urinary bladder (UB), in order to evaluate its role in follow-up controls. TPA staining intensity (SI) in urothelial cells was evaluated to improve the diagnostic accuracy of cytology. Differentiated tumor cells were strongly stained for TPA, heavier than normal urothelial cells. Undifferentiated neoplastic cells were less stained for TPA with a wide range of SI. TPA detection revealed positive cytology in 21 (75%) of the considered cases. The accuracy of our cytological findings compared with both routine examinations and subsequent histopathological diagnosis was of 95.2%. Follow-up urinary cytology limits could be reduced by TPA searching in differentiated tumor cells, deriving from low-grade neoplasms.

Andries van DamThe panel will examine the evolution of the professional workstation from a time shared terminal to powerful graphics-based personal computer connected to a resource-sharing local network. The panelists will speculate on the future evolution of both the hardware/software architecture and end user environment.Workstation development at StanfordJames H. ClarkWorkstation development at Stanford is closely linked with graphics, distributed systems and networking. Two distinct systems have evolved over the last 3 years: the SUN system and the IRIS system. The SUN is a low-cost system based upon an efficient MC68000 processor/memory design and a relatively low-performance, high-resolution bit-map display. The IRIS (Integrated Raster Imaging System) is based upon the same MC68000 design, but the graphics part of the system is a modest- to low-cost, high-performance, high-resolution, color or black and white system that uses the Geometry Engine and several other custom IC parts. Both SUN and IRIS interface to the Stanford Ethernet network, and both are being used for distributed systems research, VLSI design stations, and graphics research. In addition, IRIS will probably be used for mechanical CAD research by the mechanical engineering department and in situations where high-performance graphics is important.Improvement Goals for Workstation FacilitiesRobert M. DunnThree major areas of improvement are needed: interaction techniques that are simpler, provide faster reaction, are useful for higher-level inputs, and have user-style-oriented alternatives. The second area is for image rendering based on local capabilities, in varying degrees of image quality as a function of desired “grade of service”. The third area is to provide support to incremental model construction and approximate design evaluation. There must be evaluation techniques that can work on partial models and give one approximate results. Implications of these criteria for workstation architecture will be discussed.The application of network workstations to large-scale engineeringHarvey KriloffThe development of computerized analysis procedures during the last twenty years has been largely oriented toward providing increased analytic function. This has meant that considerations of user access to specific capabilities or ease of use of these mammoth programs are only now becoming user concerns. The emerging new technologies for display, input and their interaction, when applied to the professional workstation, will be playing an increasingly important role in satisfying these concerns. A professional workstation can be used both to improve the efficiency by which data is collected for an existing analysis program and to assist the user in the preparation of data for a formal presentation or report. This performance improvement can be accomplished through the development of user-adapted “macro procedures” for data entry, the execution of processes to check program input data for accuracy and consistency, and workstation assistance in the training of both new and existing users. At the output stage of analysis, the workstation can be used to select and reformat information prepared by the analysis program, explore the interrelationship of results from several different analyses, and derive the data for a succeeding analysis in an iterative design mode.At Boeing Computer Services, we have been exploring the benefits realized by the development of such a workstation when applied to the field of structural engineering. An interaction-rich workstation with a human-engineered executive that controls and integrates the user interface, connected to our national network of IBM, CDC and CRAY computers with a broad variety of engineering software, supplies the engineer with a full range of tools for analysis, data preparation, report writing and data relationship exploration that are only beginning to be appreciated. In the next few years it is expected that this workstation (distributed) methodology for doing engineering and other quantitative professional functions will radically change the way these analytical processes are performed.Personal Workstations in a Local NetworkDavid NelsonFor many applications, personal workstations provide a superior form of computing compared to timesharing. The requirements of workstations, however, go well beyond the facilities provided by the local computer; they must include the equivalent advantages of timesharing such as user-to-user communications, shared programs and data files, shared peripherals, etc. The preferred way to implement these functions is to interconnect all workstations by means of a high-speed local network, controlled by a distributed operating system which provides transparent access to all network resources through a network-wide virtual memory system. Additional workstation functions such as large virtual address space and a concurrent multiple-window display system significantly increase user productivity. A high resolution bit-map display system with hardware support for dynamics is an essential component. For the future we look towards both significant cost reductions and improvement in performance, as well as significantly higher level software to better implement the user-computer interface.
