Vidurinės mokyklos moksleivių (pasirinkusių gamtos mokslų dalykų profilį) reprezentacijos profesinei karjerai / Representations for a professional career of the secondary school students who have chosen the profile of natural sciences

Rukaitė, Sigita 16 August 2007 (has links)
Vykstant švietimo reformai, visas bendrasis ugdymas yra orientuotas į mokinį, jo poreikius ir gebėjimus. Mokiniui reikia prisitaikyti gyventi modernioje visuomenėje, kurioje būtina mokėti ieškoti žinių ir adekva��iai jas pritaikyti. Vienas svarbiausių uždavinių įgytas žinias pritaikyti pasirenkant profesinę veiklą. Šiandieninis pasaulis reikalauja lankstumo ir prisitaikymo. Mokiniams svarbiausia adekvačiai pasirinkti profesiją. Tam įtakos turi moksleivio aplinka: tėvai, mokytojai, bendraamžiai. Mokinių pasirengimas karjerai yra sudėtingas ugdymosi procesas. Pirmiausiai moksleiviai turi pažinti save, savo gebėjimus, polinkius. Mokykloje turi būti teikiamos profesinio informavimo, konsultavimo ir orientavimo paslaugos. Profesijos pasirinkimas yra viena aktualiausių problemų, nuo kurios tinkamo sprendimo priklauso žmogaus asmeninės gerovės augimas. Todėl labai svarbu, kad jau pats pirmasis mokinio apsisprendimas būtų sąmoningas, tikslingas, kad mokinys suprast, jog adaptacija darbo pasaulyje ir asmenybės vidinė harmonija priklauso nuo tinkamo apsisprendimo. Vykdant profesinį orientavimą bendrojo lavinimo mokyklose, turėtų būti siekiama padėti jaunimui pasirinkti mokymosi profilį, profesiją, darbinę veiklą. Profilinio mokymo esmė yra mokymosi organizavimas atsižvelgiant į moksleivių siekius, polinkius, gebėjimus, sudarant jiems galimybes pasirinkti mokymosi kryptį atitinkančius dalykus bei skirtingus jų kursus. Profiliavimo kaip ugdymo sistemos tikslas yra labiau...

The student has to adapt for living in modern society , where it is necessary to know how to look for information and to use it adequately. One of the most important goals is to use the knowledge in choosing a professional career. Today’s world requires flexibility and adaptation. The most important for students is to choose the profession adequately. The whole environment influences it: parents, teachers, friends. The preparation for the future career is a complex educational process. First the students have to know themselves, their abilities and interests. The school has to give some service of professional orientation, consultation and information. Choosing a profession is one of the most important problems and how well you choose it, your future and your personal development depend. That is why it is very important that the first choice is logical, motivated and that the student will understand that the adaptation in the working world and personal harmony depend on the right decision. During the process of professional orientation at school it has to be important to help young people to choose the learning profile, profession and practical activities. The essence of profile education is to organize it having in mind students’ objectives, interests, abilities, giving them a chance to choose the subjects and courses which are... [to full text]

WHAT ARE THE IMPRESSIONS OF OCCUPATIONAL THERAPISTS WHO USE THE SHORT SENSORY PROFILE IN ASSESSMENTS FOR DIAGNOSIS OF FETAL ALCOHOL SPECTRUM DISORDERS?

Bojkovsky, Cynthia 19 November 2010 (has links)
Introduction: The Canadian Medical Association (CMA) released guidelines for Fetal Alcohol Spectrum Diagnosis (FASD) in 2005 that attempted to equalize diagnostic practices across Canada. A multi-disciplinary neurodevelopmental assessment is expected and the occupational therapist must assess soft neurological signs, which includes sensory processing and motor development. In 2007, Northwest Partnership for FASD Research gathered a panel of OTs to consult on assessment tools who chose the Short Sensory Profile (SSP) as the main sensory processing assessment tool. Methods: Six qualitative interviews were completed for data collection. The inclusion criterion for the participants were involvement with a FASD diagnostic team and familiarity with the SSP. Qualitative data from the interviews was coded for likeness and analyzed for themes. Results: Three main themes developed from this research including: “Uncertainties about the FASD Diagnostic Process”, “Questioning the Validity of the Assessment Tool SSP” and “Strengths of the SSP”. The overaching theme that emerged was that the participants were attempting to find balance in many different ways throughout their assessments. While participants predominantly focused on concerns, they also indicated that the SSP is our best option at this time. Conclusions: Participants were not completely satisfied with using the SSP for FASD diagnostic assessments but will continue to use it. It was suggested that the panel of occupational therapists should reconvene and consider further options for assessment of sensory processing for FASD diagnostic assessments. There were also considerations for occupational therapy university education and continuing education.

A High Resolution Vertical Gradient Approach to Hydrogeologic Unit Delineation in Fractured Sedimentary Rocks

Meyer, Jessica 06 September 2013 (has links)
Prediction of contaminant transport and fate relies on robust delineation of hydrogeologic units (HGUs), which serve as the framework for all conceptual and numerical models. In layered sedimentary rock systems, contrasts in bulk vertical hydraulic conductivity (Kv) are expected to refract groundwater flow lines and be indicative of distinct HGUs. However, HGU delineation typically relies on data indirectly related to hydraulic properties or hydraulic data insensitive to contrasts in Kv. Flow system theory shows that the distribution of hydraulic head reflects contrasts in Kv. Therefore, depth-discrete and detailed (i.e. high resolution) hydraulic head profiles should identify contrasts in Kv in layered systems. This research develops, applies, and tests a high resolution head/vertical gradient profile approach to HGU delineation for sedimentary rock groundwater systems. First, the repeatability and characteristics of head profiles in sedimentary rocks were evaluated by collecting data from three contaminated field sites with contrasting geologic and flow system conditions. The shapes of the head profiles were reproducible in time and geometric in nature. The head profiles displayed thick zones with no or minimal vertical gradient separated by thinner zones with large vertical gradient indicating contrasts in Kv that did not coincide with lithostratigraphic units. Next, the method was applied at the plume scale to a site in Wisconsin with seven vertical gradient profiles collected along two cross-sections. The vertical gradient cross-sections revealed nine laterally extensive zones with contrasting Kv. The contrasts in Kv were closely associated with key sequence stratigraphic units and integration of the two data sets resulted in delineation of eight HGUs for the site. Last, comparison of these HGUs to the site contaminant mass and phase distributions, including detailed rock core contaminant profiles, provided additional verification for the HGU delineation and added insight regarding important flow and contaminant migration pathways. Application of the high resolution head/vertical gradient profile method at the Wisconsin site resulted in hydraulic measurement based, geologically integrated, and more accurately delineated HGUs. The revised hydrogeologic unit conceptual model will improve predictions of contaminant transport and fate and evaluation of remediation system designs.

The Modulating Effect of Fatty Acids on the Lipid Profile in Colon Epithelial Mucosa In Vivo.

Abrahams, Celeste H. January 2009 (has links)
<p>Several abnormal conditions, including some cancers, have been associated with changes in the membrane lipid and FA composition. Dietary fat serves as a major source of lipids and FA, particularly the polyunsaturated fatty acids (PUFA), n-6 and n-3. High intakes of n-6 PUFA have been linked to the development of colon cancer in association with low n-3 PUFA intake. Therefore understanding the differences in the lipid and FA profiles between cancer and normal cells in the colon, and the role diet plays in these factors may be invaluable in understanding their role in carcinogenesis. This study compares the lipid profile of azoxymethane (AOM) induced colon polyps to that of the surrounding mucosa tissue in rats fed a diet high in n-6 PUFA. Male Fischer rats were fed the AIN-76A diet containing sunflower oil that has high n-6 PUFA content for a period of nine months. Results indicate that the lipid and FA content of the colon polyps differs significantly from the surrounding mucosa. Colon polyps had an increase in membrane phopholipids phosphatidylcholine (PC) and phosphatidylethanolamine (PE). Changes in membrane fluidity were indicated by the decrease (p&lt / 0.05) in the PC/PE and cholesterol/phospholipids (chol/PL) ratios, and increase (p&lt / 0.05) in the polyunsaturated FA/saturated FA (P/S) ratio. Metabolism of FA was significantly altered in the polyps favouring n-6 FA metabolism and the production of prostaglandin E2. No clear indication of impaired &Delta / 6-desauturase enzyme activity was noticed. Increases in the n-6 PUFA content could be a reflection of the dietary FA intake that increases FA incorporation in the polyps. Changes in the FA parameters of the polyps, particularly an increase in C20:4n-6 and the n6/n3 ratio have been shown to contribute to the rapid growth of cancer tissue. These lipid changes associated with the development of colon polyps could provide unique targets for developing strategies in chemoprevention by dietary manipulation.</p>

A retrospective cohort analysis of the injury profile of internationally competitive surfers

Murgatroyd, Taryn Lyn January 2009 (has links)
Dissertation submitted in partial compliance with the requirements for the Master's Degree in Technology: Chiropractic, Durban University of Technology, 2009. / Modern surfing dates as far back as the 1960’s when the first amateur and professional surfing competitions were held (1). Since these humble beginnings, surfing has enjoyed a sustained growth over the last half a century, principally through increased commercialization of surfing apparel and an increased positive association with the lifestyle of surfers. Objectives: The aim of this study was to determine a retrospective cohort analysis of the injury profile of internationally competitive surfers and provide information on chronic, repetitive strain injuries suffered by them. Therefore, for the purpose of this study, the following information was gathered in order to create an injury profile: • Demographics of internationally competitive surfers competing in the Mr. Price Pro, Durban, South Africa, • Prevalence of surfing injuries, • Treatment received for injuries. Methods: This study was a retrospective, quantitative, epidemiological study (9), on the Chiropractic Student Sports Association’s (CSSA) questionnaire in order to produce a retrospective cohort analysis of the injury profile of internationally. On entry into the Chiropractic treatment facility, the surfer is requested to complete their portion of the CSSA questionnaire. Thereafter the senior intern then takes a brief case history, elaborating on the information provided by the surfer, followed by a standard clinical assessment related to the anatomical region or list of differential diagnoses based on the history. iv The study was limited to any surfer, male or female, who was competing on the World Championship Tour or the World Qualifying Series and registered to compete in the Mr. Price Pro. Results: Chronic injuries made up for 52.7% of surfing injuries, with the spine and surrounding musculature being the most commonly affected regions. Factors associated with injury were the repetitive nature of certain aspects of surfing and the age of the surfer. The findings in this study concurred with previous literature with the respect to sustaining of an injury related to surfing. However, many of the findings in this study differed to that of previous literature with respect to the common site of injury. The spine was the most common site of injury, as opposed to lower extremities as had been previously reported. The factors associated with injury also differed somewhat from previous literature. Therefore, this warrants further investigation with due consideration to the recommendations from this study.

Dosage ranging effect and safety evaluation of conjugated linoleic acid (CLA) in a hamster model

Liu, Xiaoran 09 September 2010 (has links)
The objectives of this study was to examine the efficacy and safety of graded doses of c9, t11, t10, c12 CLA isomers on body composition, energy expenditure, lipid profile and hepatic biomarkers in hamsters. Male Golden Syrian hamsters (n=105) were randomized to seven treatments (control; 1, 2, 3% of c9, t11; 1, 2, 3% of t10, c12) for 28 days. Compared with control, 1% and 3% t10, c12 had lowered food intake with all three doses of t10, c12 lowering (p<0.0001) body fat mass (g). Groups fed with 1, 2, 3% t10, c12 and 3% c9, t11 treatments showed higher lean mass compared to control and other treatment groups. However, neither body weights, nor serum HDL or triglyceride levels differed across treatment groups. The 3% t10, c12 groups exhibited higher (p<0.0001) cholesterol and LDL-C levels compared to control or other treatment groups. The 2% and 3% t10, c12 groups also presented elevated ALT level (p<0.05). The present data suggest that 3% t10, c12 possess potential adverse effects on liver and posing unfavorable change in lipid profile.

Real-time beam-profile monitor for a medical cyclotron

Hoehr, C., Hendriks, C., Uittenbosch, T., Cameron, D., Kellog, S., Gray, D., Buckley, K., Verzilov, V., Schaffer, P. 19 May 2015 (has links) (PDF)
Introduction Measuring the beam profile on a medical cyclo-tron in real time can aid in improved tuning of the cyclotron and give important information for a smooth operation. Typically the beam profile is measured by an autoradiography technique or even by a scintillator that can be viewed in real time [1, 2]. Another method is to use collimators in front of the target to assess the beam center-ing [3]. All these methods have potential draw-backs including; an inability to monitor the beam in real time for the radiograph, exhibiting a non-linear correlation in signal response to the power deposited for a scintillator, and not providing a 2-dimensional profile of the complete beam for collimators. Our goal was to design a realtime, linear, 2-dimensional beam-profile monitor that is able to withstand the high power of a PET cyclotron. Material and Methods The beam-profile monitor (PM) is designed for the TR13, a 13MeV negative hydrogen-ion cyclotron at TRIUMF. The design follows the concept of a ‘harp’ monitor, widely used at TRIUMF for tuning proton and radioactive ion beams, and is installed on the extraction port without separation from the tank vacuum. The TR13 monitor is designed to withstand a 13 MeV proton beam with a beam current of up to 25 µA, has an active area of 10 by 10 mm and does not affect the 10-7 torr tank vacuum. The device consists of a water-cooled Faraday cup made out of aluminium for low activation and two orthogonal rows of eight tungsten electrodes each mounted on a water-cooled support frame. Electrodes are spaced 1 mm apart from each other, see FIG. 1. The electrodes are electrically isolated from each other and each has a current pickup soldered to it. The material and the shape of the electrodes are optimized to withstand the deposited power of the proton beam. A voltage of -90 V is applied to the electrodes to repel secondary electrons and prevent crosstalk between neighbouring electrodes. The electrode current is amplified using a custom current amplifier, and read by an ADC. From there, the current data is displayed on a PC. This allows one to observe changes of the beam profile in real time. The electronics are designed to read out all sixteen channels in parallel, or, if only a limited number of ADC channels are available, to cycle through the different channels. In our current setup all sixteen channels are read out simultaneously. Results and Conclusion The beam-profile monitor provides a real-time representation of the proton beam, see FIG. 2. The data can also be recorded and analyzed at a later time. The linearity of the monitor has been measured up to 30 µA of proton beam current [4]. With the use of the monitor, it was possible to increase the output of the ion source into the target by 50% in comparison to the standard tune.
