Tutkimuksessa selvitettiin, miten ammatillisen koulutuksen ensimmäisen vuosikurssin opiskelijat kokevat siirtymän peruskoulusta toiselle asteelle ja millaista tukea he toivoisivat siirtymän aikana. Teoreettisen tarkastelun kehyksenä käytettiin ekologista lähestymistapaa ja siirtymää tarkasteltiin kolmiosaisena jatkumona, jossa yksilö on niin sanotussa liminaaliprosessissa. Tutkimusaineisto (N=94) kerättiin sähköisellä kyselyllä ja se toteutettiin monimenetelmäisesti. Määrällistä aineistoa analysoitiin kuvailevilla tilastollisilla menetelmillä ja laadullista aineistoa tematisoitiin teoriaohjautuvasti. Avointen vastausten perusteella tuen tarpeiden pääteemat vaihtelivat siirtymäprosessin aikana. Tuen tarpeet voidaan jakaa tiedollisiin tarpeisiin, psykososiaalisen tuen ja arjen hallinnan tarpeisiin sekä opintoihin liittyviin tuen tarpeisiin. Siirtymäprosessin aikana eniten tukea kaivattiin stressinhallintaan, opintojen suunnitteluun ja jännittämiseen. Näillä tuen tarpeilla oli yhteys sukupuoleen siten, että tytöt kaipasivat tilastollisesti merkitsevästi useammin tukea kuin pojat. Kaikista suurimpina tuen antajina nuorille olivat läpi siirtymäprosessin vanhemmat ja ystävät. Kaksi eniten tukea antavaa ammattiryhmää olivat opinto-ohjaajat ja luokanvalvojat/omanohjaajat. Noin kolmannes opiskelijoista ei kokenut tarvitsevansa tukea lainkaan. Lisäksi noin kolmanneksella vastaajista ei ollut selkeää mielikuvaa itseä koskevien tietojen siirrosta oppilaitosten välillä. Tulokset auttavat hahmottamaan ekologisessa lähestymistavassa tarkasteltavien eri kasvuympäristöjen ja niiden yhteistyön merkitystä siirtymävaiheen kannalta.

Estimación de la presión muscular a partir de la medición de la presión de oclusión en ventilación mecánica invasiva
Authors: García Guillermina , Gigena Santiago 
Published: November 2022

La ventilación mecánica asistida debe ser optimizada para mantener un esfuerzo muscular adecuado. La herramienta de excelencia para monitorizarlo es la manometría esofágica, ya que permite calcular la presión desarrollada por los músculos inspiratorios. Sin embargo, es invasiva y poco utilizada en la práctica diaria.
Bertoni et al. proponen que, a partir de una maniobra de oclusión espiratoria, la deflexión de la presión de la vía aérea provocada por el esfuerzo del paciente contra la vía aérea ocluida (ΔPocc) permite estimar el valor de presión muscular de manera sencilla y no invasiva.
En la actualidad, gran parte de los ventiladores tienen la posibilidad de realizar maniobras de oclusión en modos controlados y espontáneos. El objetivo del presente paso a paso es describir el procedimiento de la medición y el cálculo de la presión muscular a partir de la ΔPocc.
Analysis Methods for Evaluating Motions and Accelerations of Planning Boats in Waves
Authors: Zseleczky John , McKee Glenn 
Published: November 2022

For some time, the experimental testing or model planing hulls in rough water has been done by towing tanks throughout the world. The common goal or all these efforts is to provide designers with information that will give them a better understanding or the effects of hull form on the response to waves -in terms of motions, accelerations, added resistance, loads, and operating conditions.
It has become increasingly common to analyze the time series data from these experiments using a peak-trough identification. technique (PKT). Once peaks and troughs are identified, they are sorted and averaged over subsets to obtain averages of the 1/m-th highest statistics - which are the statistics currently used by planing boat designers.
There are two problems involved with the current approach, one is conceptual and the other is operational: 1) 1 /m-th highest statistics involve the construction of averages based on the number or oscillations observed, however there are no rules for determining the number or small oscillations to be rejected, consequently, 2) the PKT Method requires subjective input from the user that can affect the statistics.
This presentation is a joint effort between the Davidson Laboratory and Naval Academy Hydromechanics Laboratory to inform both designers and other experimentalists about the care that must taken in using the average or the 1/m-th highest statistics and to suggest alternative measures or motion and acceleration response that are objective and easy to understand.
It is also hoped that this paper will start a discussion with designers about the specific nature of the hydrodynamic data needed to enable more mission and cost effective boat designs to be produced.
Construction and Commissioning of the Offshore Engineering and Seakeeping Basin at the Institute for Marine Dynamics
Authors: Murray J. , Fudge G. 
Published: November 2022

The National Research Council of Canada is presently constructing and preparing to commission a 75 m x 32 m x 3.5 m Offshore Engineering and Seakeeping Basin at the Institute for Marine Dynamics in St. John's, Newfoundland. The Basin will be capable of simulating waves, wind and current, for use in both commercial and research programs. The first stage of commissioning and calibration will focus on preparing the Basin, scheduled for completion in February 1990, for commercial testing of moored and free running vessels.
Waves are gene rated in the Basin by means of a 192 segment wave machine, mounted in a "J" configuration. Short and long-crested monochromatic and random waves will be generated using the snake principle. Passive wave absorption is utilized in the Basin using expanded metal sheets of varying porosities and spacings. These are located at all Basin wall locations not supporting wave generators.
A bank of 24 analog controlled fans is used to generate wind. Turbulence spectra and velocity profiling are established by fluctuating the speed of the fans using precalibrated drive signals. Surface current is generated by setting up water circulation within the Basin. Submersible pumps are used to charge manifolds positioned at various levels below the surface.
The data acquisition system, controlled by a microVAX-II computer, is capable of variable rate sampling of 128 channels of A/0 and can simultaneously output 16 channels of DIA. The microVAX is networked to a local VAX 3200 used for synthesis of drive signals and test data reduction and analysis. Model motions in six degrees-of-freedom are measured using an optical tracking system, consisting of three vertical and two horizontal cameras, and light emitting diodes positioned on the model.
Multi-Directional Seas - A practical Tool for Evaluating the Feasibility of Marine Operations
Authors: Edwards R. 
Published: November 2022

The timing and feasibility of installing skyscraper sized structures in the ocean depends strongly upon limitations dictated by motion response of complex combinations of heavy 11ft vessels, barges and the structures to be installed, all Joined by elastic tethers. Exposure of these systems to long crested and Irregular seas in a model test does not produce a complete picture of the response to a realistic environment.
In several recent model test programs to support the assessment of the feasibility of Installing large structures, short crested seas have been generated and imposed on combinations of semi-submerged vessels and jacket structures in partial contact with the bottom. In some cases, the expectation that short crested seas would result in less severe system loads and motions was not realized.
This paper will discuss the methodology employed to set up the complex physical simulation of lowering a 10,000 + ton offshore tower and mating It to a predrilled template in a North Sea environment.
The techniques used to generate the multi-directional seas will be presented and the resulting functions characterizing the measured model sea will be presented and compared to the desired.
The responses of a complex moored system of structure and semi-submersible lift ship to irregular and short crested seas will be presented and compared.
The effects of Reynolds Number, Section Shape, and Turbulence Stimulation on the Lift of a Series of Model Control Surfaces
Authors: Lewandowski Edward 
Published: November 2022

A series of model control surfaces with equal areas but varying aspect ratio, was lasted in a towing tank on a ground board. The size of the fins, approximately 3 inches span and two inches chord, is typical of control surfaces used on models which are about five feel long. Lift and drag on the fins were measured over a range of angles of attack of 0 to 35 degrees. The tests covered a range of chord-based Reynolds numbers between 42,000 and 150,000.
Two sets of fins were tested, one having flat-plate sections and the other having NACA 0015 sections. The fins were each tested with and without turbulence stimulation In the form of tape with a serrated leading edge placed at 5% of the local chord aft of the leading edge of the foil.
The study has shown that the lift of the NACA 0015 fins was insensitive to Reynolds number in the range of the tests, and that the lift rates compare well with the results of previous tests carried out at high Reynolds numbers. Differences were noted in the characteristics of flat-plate and NACA 0015 fins which would indicate that the use of flat plates in the place of foil-shaped fins to save model construction cost is not good practice. Turbulence trips increase the measured drag, as expected, but also reduce the lift rate, most noticeable on the flat-plate fins.
Drag Reduction with Riblets on Rowing Shells
Authors: Coder David , Walker David , McKelvey Dennis , Enzinger Steven 
Published: November 2022

An experiment is described in which riblets, which are longitudinal surface groves that have been shown by NASA to reduce turbulent flow skin friction on flat plates by much as 8 percent, are used to attempt to reduce the overall vehicle drag of rowing shells. Two single rowing shells, borrowed from the USNA rowing team and ballasted (with the outriggers removed) to represent a 200 lbf rower, were attached to the drag balance of the carriage of the USNA tow tank and towed at steady velocities from 4 to 20 ft/sec in 2 ft/sec increments. The attachment mechanism allowed the shells to move freely in heave and pitch (sinkage and trim) which were measured with a sonic height probe and angleometer, respectively. Various surface conditions tested include bare hull, flat (non-ribleted) tape, and riblet tape (cleaned and uncleaned) in combination with two sizes of trip wire and three trip locations. The particular riblet tape used provided a surface geometry of saw-tooth pattern transverse to the flow with a height and spacing of 0.003 in.
This provided an optimum non-dimensional height (s+) recommended by Walsh and Lindemann (1984) of NASA of 12 to 15 over most of the shell length for the higher velocities. The overall vehicle drag results are compared with and without riblets and with and without trip wire. Riblet drag reductions of between 3 and 5 percent are observed. The trip wire results showed an increase in drag due to their parasite drag at. the lower velocities but a drag reduction at the higher velocities. Predictions of the viscous component of the drag difference between configurations are developed including the effects of sinkage and trim. The predictions compare qualitatively with the experimental results except for the apparent drag reduction with a trip wire at the higher velocities.
