Läheisen rooli ja tuen tarve iäkkään kotiutuessa arviointi- ja kuntoutusosastolta

Tämän tutkimuksen tarkoituksena oli kuvata läheisen roolia ja tuen tarvetta iäkkään kotiutuessa arviointi- ja kuntoutusosastolta. Tavoitteena oli saada tietoa iäkkäiden kotiutusprosessista läheisen näkökulmasta ja muodostaa käsitteellinen malli, jossa on tyypitelty läheisen erilaiset roolit, niihin vaikuttavat tekijät ja tuen tarpeet iäkkään kotiutuessa arviointi- ja kuntoutusosastolta. Tutkimus oli kuvaileva tutkimus, jossa sovellettiin metodologista triangulaatiota. Kotiutuva iäkäs nimesi läheisen (n=14), jolta kerättiin tutkimusaineistoa teemahaastattelulla ja kyselyllä (COPE -indeksi, Carers of Older People in Europe). Rekrytointi tapahtui viidellä arviointi- ja kuntoutusosastolla Etelä-Suomessa kesällä 2015. Teemahaastattelu analysoitiin induktiivisella sisällönanalyysillä ja kyselyn (COPE -indeksi) vastauksista laskettiin prosenttiosuudet ja kolmella osa-alueella laskettiin lisäksi summapisteiden keskiarvot. Tutkimuksen päätulos tuli teemahaastattelun sisällön analyysistä, jota vahvistettiin kyselystä (COPE -indeksi) saaduilla tuloksilla. Tämän tutkimuksen tuloksena syntyi käsitteellinen malli läheisen roolista ja tuen tarpeista iäkkään kotiutuessa arviointi- ja kuntoutusosastolta. Läheisen rooli jakautui neljään päärooliin, jotka olivat iäkkään arjen auttajan rooli, edunvalvojan rooli, tukijan rooli ja vastuunkantajan rooli. Arjen auttajan rooliin kuului läheisen käytännön järjestäjän rooli ja kodinhoitajan rooli. Edunvalvojan rooliin sisältyi iäkkään terveydellinen edunvalvojan rooli, taloudellinen edunvalvojan rooli ja puolestapuhujan rooli. Tukijan rooli muodostui iäkkään virkistäjän roolista ja muutokseen sopeuttajan roolista. Näissä rooleissa toimimiseen vaikuttavia tekijöitä olivat läheisen ja iäkkään välinen suhde, läheisen oma elämä, rooliin saatu tuki ja roolin mielekkyys. Läheisen roolissa tuen tarpeita olivat arjen tuki, roolissa toimimisen tuki, rohkaiseva ja sosiaalinen tuki. Kyselyn (COPE -indeksi) tulokset täydensivät kuvausta läheisen rooliin vaikuttavista tekijöistä ja tuen tarpeista. Keskeistä tuloksissa oli, että läheisillä oli hyvä suhde iäkkäisiin, avustaminen koettiin vaivan arvoiseksi ja muiden ihmisten koettiin arvostavan heidän toimimistaan iäkkään avustajana. Ajoittain avustaminen koettiin liian vaativana tuoden kielteisiä vaikutuksia omaan tunne-elämään ja fyysiseen terveydentilaan, tunnettiin olevan ansassa. Läheiset tunsivat saavansa hyvin tukea perheeltä, mutta sosiaali- ja terveyspalveluista saatavassa tuessa koettiin parannettavaa. Tämän empiirisen tutkimuksen tuloksena tuotettu käsitteellinen malli todentaa läheisen roolin monimutkaisuuden ja moniulotteisuuden. Läheisen roolissa tarvitaan erityistä tukea tilanteiden muuttuessa, kuten kotiutustilanteissa. Tutkimuksen tuloksia voidaan hyödyntää kehitettäessä iäkkäiden yksilöllistä kotiutumista ja tilanteeseen sopivia läheisen roolia tukevia palveluita.

Alhaisen volatiliteetin anomalia Suomen osakemarkkinoilla

Tutkielman tavoitteena on selvittää esiintyykö Suomen osakemarkkinoilla alhaisen volatiliteetin anomaliaa. Tutkielman tavoitteeseen vastataan työn empiirisessä osassa analysoimalla Suomen osakemarkkinoilla listattujen osakkeiden tuottoaikasarjoja. Tutkielmassa tarkastellaan myös finanssikriisin vaikutusta anomalian ilmenemiseen. Tutkimus sijoittuu aikavälille tammikuusta 2001 tammikuuhun 2015. Tutkielmassa muodostetaan portfolioita osakkeiden historiallisen volatiliteetin mukaan. Näiden portfolioiden menestymistä suhteessa markkinoihin arvioidaan absoluuttisten tuottojen, Sharpen luvun sekä Jensenin alfan avulla. Markkinaindekseinä käytetään OMXH CAP -indeksiä sekä tutkimusaineiston pohjalta muodostettua markkinaportfoliota. Kaikkein parhaimman absoluuttisen tuoton on saanut vuodesta 2001 vuoteen 2015 sijoittamalla keskiverron volatiliteetin osakkeisiin. Parhaan riskikorjatun tuoton on kuitenkin saavuttanut sijoittamalla alhaisen volatiliteetin osakkeisiin. Tutkielmassa löydetään todisteita alhaisen volatiliteetin anomalian esiintymisestä Suomen osakemarkkinoilla koko tutkimusaineisto huomioon ottaen. Tutkielman ehkä mielenkiintoisin löydös on kuitenkin huomio alhaisen volatiliteetin anomalian häviämisestä Suomen osakemarkkinoilta finanssikriisin jälkeen. Ennen finanssikriisiä esiintynyt erittäin vahva alhaisen volatiliteetin osakkeiden ylisuoriutuminen hävisi täysin finanssikriisin jälkeen. Toisin sanoen riskin ja tuoton suhde on kääntynyt päälaelleen finanssikriisin jälkeen, eikä alhaisen volatiliteetin anomaliaa voida enää sanoa esiintyvän.

Détection et caractérisation de naines brunes et exoplanètes avec un filtre accordable pour applications dans l'espace

Cette thèse porte sur la capacité à détecter des compagnons de faible intensité en présence de bruit de tavelures dans le contexte de l’imagerie à haute gamme dynamique pour l’astronomie spatiale. On s’intéressera plus particulièrement à l’imagerie spectrale différentielle (ISD) obtenue en utilisant un étalon Fabry-Pérot comme filtre accordable. Les performances d’un tel filtre accordable sont présentées dans le cadre du Tunable Filter Imager (TFI), instrument conçu pour le télescope spatial James Webb (JWST). La capacité de l’étalon à supprimer les tavelures avec ISD est démontrée expérimentalement grâce à un prototype de l’étalon installé sur un banc de laboratoire. Les améliorations de contraste varient en fonction de la séparation, s’étendant d’un facteur 10 pour les séparations supérieures à 11 lambda/D jusqu’à un facteur 60 à 5 lambda/D. Ces résultats sont cohérents avec une étude théorique qui utilise un modèle basé sur la propagation de Fresnel pour montrer que les performances de suppression de tavelures sont limitées par le banc optique et non pas par l’étalon. De plus, il est démontré qu’un filtre accordable est une option séduisante pour l’imagerie à haute gamme dynamique combinée à la technique ISD. Une seconde étude basée sur la propagation de Fresnel de l’instrument TFI et du télescope, a permis de définir les performances de la technique ISD combinée avec un étalon pour l’astronomie spatiale. Les résultats prévoient une amélioration de contraste de l’ordre de 7 jusqu’à 100, selon la configuration de l’instrument. Une comparaison entre ISD et la soustraction par rotation a également été simulée. Enfin, la dernière partie de ce chapitre porte sur les performances de la technique ISD dans le cadre de l’instrument Near-Infrared Imager and Slitless Spectrograph (NIRISS), conçu pour remplacer TFI comme module scientifique à bord du Fine Guidance Sensor du JWST. Cent quatre objets localisés vers la région centrale de la nébuleuse d’Orion ont été caractérisés grâce à un spectrographe multi-objet, de basse résolution et multi-bande (0.85-2.4 um). Cette étude a relevé 7 nouvelles naines brunes et 4 nouveaux candidats de masse planétaire. Ces objets sont utiles pour déterminer la fonction de masse initiale sous-stellaire et pour évaluer les modèles atmosphériques et évolutifs futurs des jeunes objets stellaires et sous-stellaires. Combinant les magnitudes en bande H mesurées et les valeurs d’extinction, les objets classifiés sont utilisés pour créer un diagramme de Hertzsprung-Russell de cet amas stellaire. En accord avec des études antérieures, nos résultats montrent qu’il existe une seule époque de formation d’étoiles qui a débuté il y a environ 1 million d’années. La fonction de masse initiale qui en dérive est en accord avec des études antérieures portant sur d’autres amas jeunes et sur le disque galactique.

OpenSearch-geo: the simple standard for geographic web search engines

When publishing information on the web, one expects it to reach all the people that could be interested in. This is mainly achieved with general purpose indexing and search engines like Google which is the most used today. In the particular case of geographic information (GI) domain, exposing content to mainstream search engines is a complex task that needs specific actions. In many occasions it is convenient to provide a web site with a specially tailored search engine. Such is the case for on-line dictionaries (wikipedia, wordreference), stores (amazon, ebay), and generally all those holding thematic databases. Due to proliferation of these engines, A9.com proposed a standard interface called OpenSearch, used by modern web browsers to manage custom search engines. Geographic information can also benefit from the use of specific search engines. We can distinguish between two main approaches in GI retrieval information efforts: Classical OGC standardization on one hand (CSW, WFS filters), which are very complex for the mainstream user, and on the other hand the neogeographer’s approach, usually in the form of specific APIs lacking a common query interface and standard geographic formats. A draft ‘geo’ extension for OpenSearch has been proposed. It adds geographic filtering for queries and recommends a set of simple standard response geographic formats, such as KML, Atom and GeoRSS. This proposal enables standardization while keeping simplicity, thus covering a wide range of use cases, in both OGC and the neogeography paradigms. In this article we will analyze the OpenSearch geo extension in detail and its use cases, demonstrating its applicability to both the SDI and the geoweb. Open source implementations will be presented as well

Subsurface drip irrigation emitter spacing effects on soil water redistribution, corn yield and water productivity

Emitter spacings of 0.3 to 0.6 m are commonly used for subsurface drip irrigation (SDI) of corn on the deep, silt loam soils of the U.S. Great Plains. Subsurface drip irrigation emitter spacings of 0.3, 0.6, 0.9 and 1.2 m were examined for the resulting differences in soil water redistribution, corn grain yield, yield components, seasonal water use, and water productivity in a 4‐year field study (2005 through 2008) at the Kansas State University Northwest Research‐Extension Center, Colby, Kansas. The results indicate that there is increased preferential water movement along the dripline (parallel) as compared to perpendicular to the dripline and that this phenomenon partially compensates for wider emitter spacings in terms of soil water redistribution. Corn yield and water productivity (WP) were not significantly affected by the emitter spacing with application of a full irrigation regime

Efeito da fotoativação com LED sobre a microdureza de um compósito em cavidades com diferentes profundidades

O objetivo deste estudo foi avaliar o comportamento de três aparelhos fotoativadores, sendo que dois aparelhos utilizam a tecnologia de diodos emissores de luz (LED) (Radii-SDI; Single V-Bio art) e o ultimo é um aparelho convencional de lâmpada halógena (XL-2500-3M ESPE), sendo que o primeiro apresenta o diodo emissor de luz na extremidade do aparelho; o segundo apresenta ponteira de fibra óptica turbo e o terceiro apresenta ponteira de fibra óptica convencional. O desempenho dos aparelhos foi analisado por meio da análise de microdureza do fundo de um incremento de 2mm do compósito Z250 (3M ESPE), submetido à polimerização em diferentes profundidades: 2mm, 4mm, 6mm e 8mm. Em todos os casos, o tempo de polimerização adotado foi de 20 s. Para obtenção dos corpos de prova, foi utilizada uma matriz de dentina com uma cavidade de 3mm de diâmetro por 2mm de espessura. Para simular as diferentes profundidades de 2mm, 4mm, 6mm e 8mm, foram utilizados espaçadores de dentina em forma de anel com 2mm, 4mm, e 6mm de espessura sobre a matriz. Para o ensaio de microdureza, foram confeccionados cinco corpos de prova para cada combinação entre aparelho fotoativador e as quatro profundidades, totalizando 60 corpos de prova. . O ensaio foi realizado 15min após a polimerização. Os valores de microdureza foram obtidos a partir de cinco endentações em cada corpo de prova. Os resultados obtidos foram submetidos à análise de variância e ao teste Tukey para comparação entre os aparelhos, em cada profundidade (α=0,05). Os valores médios e desvio padrão da microdureza obtidos com os aparelhos Radii(R), Single V (S) e XL-2500(XL), a 2mm, foram respectivamente: 55,16 (±1,66), 58,56 (±1,77), 51,15 (±2,08), mostrando diferença significativa entre eles, sendo que o melhor desempenho foi obtido pelo S seguido pelo R e pelo XL. A 4mm, os valores foram R= 52,23 (±1,66 ); S= 49,04 (±2,04); XL= 47,34 (±2,69), com melhor desempenho do R em relação a XL, porém sem diferença do S. A 6mm, os valores foram R= 46,40 (±1,07); S= 43,64 (±1,56); XL= 42,12 (±1,72). Com melhor desempenho do R, seguidos pelo S e XL que não mostraram diferença entre si. Já a 8mm, os valores foram R= 41,96 (±1,09); S= 38,36(± 0,87); XL= 40,16 (±1,70), com melhor desempenho do R seguido pelo XL e este pelo S, mostrando diferença significativa entre eles. Comparando os aparelhos LED com a lâmpada halógena, pode-se observar que o Radii teve um desempenho superior a ela em todas as profundidades. Já o Single V foi superior na profundidade de 2mm, similar em 4mm e em 6mm e inferior em 8mm, mostrando que os aparelhos LED tiveram um comportamento diferenciado que talvez possa ser atribuído à presença de uma ponteira turbo no Single V. Também com base nos resultados foi possível concluir que houve uma redução significativa, dos valores de microdureza do fundo do material restaurador com o aumento da profundidade da cavidade para todos os aparelhos.

Electrolocation-communication discharges of the fish Gymnotus carapo L. (Gymnotidae: Gymnotiformes) during behavioral sleep

Technical problems have hampered the study of sleep in teleosts. The electrical discharges of Gymnotus carapo L. (Gymnotidae: Gymnotiformes) were monitored to evaluate their ease and reliability as parameters to study sleep. The discharges were detected by electrodes immersed in a glass aquarium and were recorded on a conventional polygraph. G. carapo showed conspicuous signs of behavioral sleep. During these periods, opercular beat rates were counted, electric discharges recorded, and the sharp discharge increase (SDI) of the orienting reflex was investigated. All 20 animals monitored maintained electrical discharges during behavioral sleep. The discharge frequencies during sleep (50.3 ± 10.4 Hz) were not significantly different from those observed when the fish was awake and inactive (57.2 ± 12.1 Hz) (Wilcoxon matched-pairs signed-ranks test, P>0.05). However, the SDI, which was prevalent in the awake fish, was not observed during periods of behavioral sleep. Additional observations showed that the species had cannibalistic habits. When presented with electrical discharges from a conspecific, the sleeping fish showed an initial decrease or pause in discharge frequency, while the awake fish did not have this response. We conclude that the electrical discharges of G. carapo were not conspicuous indicators of behavioral sleep. Discharges may have been maintained during sleep for sensory purposes, i.e., conspecific detection and avoidance of cannibalistic attacks.

As possibilidades de uso de ferramentas da informática: software para análise de dados qualitativos e ISD

The objective of the present article is to identify and discuss the possibilities of using qualitative data analysis software in the framework of procedures proposed by SDI (socio-discursive interactionism), emphasizing free distribuited software or free versions of commercial software. A literature review of software for qualitative data analysis in the area of social sciences and humanities, focusing on language studies is presented. Some tools, such as: Wef-tQDA, MLCT, Yoshikoder and Tropes are examined with their respective features and functions. The software called Tropes is examined in more detail because of its particular relation with language and semantic analysis, as well as its embeded classification of linguistic elements such as, types of verbs, adjectives, modalizations, etc. Although trying to completely automate an SDI based analysis is not feasible, the programs appear to be powerful helpers in analyzing specific questions. Still, it seems important to be familiar with software options and use different applications in order to obtain a more diversified vision of the data. It is up to the researcher to be critical of the analysis provided by the machine.

Microleakage in primary teeth restored by conventional or bonded amalgam technique.

The aim of this in vitro study was to evaluate marginal leakage in class V restorations in primary teeth restored with amalgam, using three different techniques. Thirty maxillary anterior primary teeth, clinically sound and naturally exfoliated, were used. In group 1 (n = 10), two thin layers of a copal varnish (Cavitine) were applied. In group 2 (n = 10), Scotchbond Multi-Purpose Plus, a dual adhesive system, was used according to manufacturer instructions. In group 3 (n = 10), One-Step adhesive system in combination with a low-viscosity resin (Resinomer) were used according to manufacturer instructions. All samples were restored with a high-copper dental amalgam alloy (GS 80, SDI). After restoration, the samples were stored in normal saline at 37 degrees C for 72 h. The specimens were polished, thermocycled (500 cycles, 5 degrees and 55 degrees C, 30-s dwell time) and impermeabilized with fingernail polish to within 1.0 mm of the restoration margins. The teeth were then placed in 0.5% methylene blue for 4 h. Finally, the samples were sectioned and evaluated for marginal leakage. The Kruskal-Wallis test showed that the filled adhesive resin (group 3) had the least microleakage. There was no significant difference between groups 1 and 2.

Effects of bleaching with carbamide peroxide gels on microhardness of restoration materials

The objective of this in vitro study was to quantitatively assess the effects of bleaching with 10 and 15% carbamide peroxide (CP) on restoration materials by performing superficial microhardness analysis. Acrylic cylindrical containers (4 x 2 mm) were filled with the following restoration products: Charisma (Heraues Kulzer, Vila Santa Catarina, São Paulo, Brazil), Durafill VS (Heraeus Kulzer), Vitremer (3M, Sumaré, São Paulo, Brazil), Dyract (Dentsply, Petrópolis, Rio de Janeiro, Brazil), and Permite C (SDI, São Pauio, São Paulo, Brazil). Sixty samples were prepared of each restoration material. Twenty samples received bleaching treatment with 10% CP, 20 samples received bleaching treatment with 15% CP, and 20 samples were kept submerged in artificial saliva, which was replaced daily. The treatment consisted of immersion of the specimens in 1 cm3 of CP at 10 and 15% for 6 hours per day during 3 weeks, whereupon the test specimens were washed, dried, and kept immersed in artificial saliva for 18 hours. Then the test and control specimens were analyzed using a microhardness gauge. The Knoop Hardness Number (KHN) was taken for each test and control specimen at five different locations by applying a 25 g force for 20 seconds. The values obtained were transformed into KHNs and the mean was calculated. The data were submitted to statistical analysis by analysis of variance and Tukey test, p < .05. The means/standard deviations were as follows: Charisma: CP 10% 38.52/4.08, CP 15% 34.31/6.13, saliva 37.36/4.48; Durafill VS: CP 10% 18.65/1.65, CP 15% 19.38/2.23, saliva 18.27/1.43; Dyract AP: CP 10% 30.26/2.81, CP 15% 28.64/5.44, saliva 33.88/3.46; Vitremer: CP 10% 28.15/3.04, CP 15% 17.40/3.11, saliva 40.93/4.18; and Permite C: CP 10% 183.50/27.09, CP 15% 159.45/5.78, saliva 215.80/26.15. A decrease in microhardness was observed for the materials Dyract AP, Vitremer, and Permite C after treatment with CP at 10 and 15%, whereas no effect on either of the two composites (Charisma and Durafill) was verified. CLINICAL SIGNIFICANCE: The application of the carbamide peroxide gels at 10 and 15% did not alter the microhardness of the composite resins Charisma and Durafill. In situ and clinical studies are necessary to enable one to conclude that the reduction in microhardness of the materials effectively results in clinical harm to the restorations.
