Elämäntapatutkimus kauneudenhoitoalan opiskelijoille

Tämän opinnäytetyön tarkoitus on selvittää kauneudenhoitoalan opiskelijoiden elämäntapoja ja analysoida niiden vaikutuksia koulussa jaksamiseen sekä opintojen etenemiseen. Opinnäytetyö on tehty yhteistyössä Stadin ammattiopiston kauneudenhoitoalan koulutusyksikön kanssa. Tutkimuksen tavoite on tuoda esille elämäntapojen vaikutus opintoihin, ja mahdollisesti saada nuoret opiskelijat ymmärtämään valintojensa merkitys. Elämäntavat näkyvät väistämättä jokaisen ihmisen arjessa, ja nuorena opitut tavat jatkuvat monesti myös aikuisiällä. Asioiden merkitys on hyvä ymmärtää jo nuorena rakennettaessa tulevaisuutta kouluttautumalla työelämään. Tutkimuksessa kävi ilmi, että elämäntavat vaikuttavat nuorten opintoihin tutkimustulosten perusteella vähemmän kuin ennakko-oletuksena oli. Vastausten mukaan kauneudenhoitoalan opiskelijoiden elämäntavat ovat melko hyvät, eikä heillä juurikaan ole poissaoloja koulusta huonojen elintapojen seurauksena. Kuitenkin esille nousi se, että mikäli poissaoloja koulusta on kertynyt, vaikuttaa se opiskelumotivaatioon ja opintojen etenemiseen. Päällimmäisenä tutkimuksessa nousi esille, että selkein syy poissaoloihin vaikuttaisi tutkimuksen mukaan olevan unenpuute, jota esiintyi noin puolella vastaajista. Suurimmalla osalla opiskelijoista ei ole säännöllistä vuorokausirytmiä, vaikka opiskelu tapahtuu arkipäivisin samaan aikaan. Unen määrän ja laadun koetaan myös vaikuttavan opinnoissa jaksamiseen. Noin puolella vastaajista ei myöskään ole säännöllistä ruokailurytmiä, mutta sen ei koeta kuitenkaan juurikaan vaikuttavan opintoihin negatiivisesti. Tutkimuksen tuloksia voidaan hyödyntää ammatillisissa oppilaitoksissa, kun pyritään ymmärtämään opiskelijoiden opinnoissa jaksamisen syitä sekä opiskelumotivaatiota.Survey of lifestyle habits among beauty care students The purpose of this thesis was to survey the beauty care students’ lifestyle habits and analyse the effects of those habits on the students’ well-being and performance at school. The thesis was done in cooperation with Helsinki Vocational College. The aim of this study was to find out how lifestyle habits affect the studies and hopefully make the young students understand the implications of their choices. The lifestyle choices have a great impact on how we live and the habits adopted early are often carried into adulthood. The significance of one’s choices is important to take into account when getting ready for the future job market. According to the results of this study, lifestyle habits affect the students’ performance less than was assumed. The results showed that the beauty care students’ lifestyle habits are quite good and they did not have many lifestyle related absences from classes. Yet, when absences pile up, it implies problems concerning motivation and advancement in studies. The main finding was that the most common reason for absences is sleep deprivation, which was experienced by half of the students who participated in this study. The majority of the students did not have a regular daily rhythm even though they studied daily at regular times. The quantity and quality of sleep were seen as affecting the studies. About half of the respondents did not have a regular dietary schedule either, but it was not seen as affecting the studies negatively. The results of this study can be used at vocational colleges when trying to understand the issues related to the students’ performance and motivation in studies

Kannattavuuden arviointi yksityismetsätaloudessa

Opinnäytetyön tavoitteena oli kannattavuuden arviointi esimerkkitilalla metsätalouden ohjelmistoja hyödyntäen ja arvioida ohjelmistojen soveltuvuutta yksityismetsätalouden käyttöön. Työn teoriaosuuteen perehdyttiin tutustumalla Suomen metsävaroihin ja metsänomistajarakenteeseen. Met-sätalouden kannattavuuden perustana olivat teoriapohja liittyen metsätalouden tuloihin, menoihin ja verotukseen. Työssä aineistona käytettiin vuonna 2015 laadittua metsäsuunnitelmaa. Tutkimusmenetelminä olivat esimerkkitilan kannattavuuden arviointi Metsätalouden kannattavuuslaskuria ja Motti-ohjelmistoa hyödyntäen. Metsätalouden kannattavuuslaskurin avulla laadittiin yhteenveto metsätilan taloudellisista tunnusluvuista, taselaskelmasta, tuloslaskelmasta ja kassavirran kehityksestä. Motti-ohjelmistolla laadittiin esimerkkitilan edustaville kuvioille kehitysennusteet ja selvitettiin erilaisten metsänkäsittelytoimenpiteiden taloudellista kannattavuutta. Keskimääräinen liiketulos metsätilalla oli 10 073 euroa vuodessa. Metsätilan hehtaarikohtainen liiketulos oli 45 euroa vuodessa. Metsätilan kirjanpidon tulos säilyi positiivisena lukuun ottamatta tarkastelujakson viimeistä vuotta, jolle ei ajoittunut metsäsuunnitelman mukaisia hakkuita. Esimerkkitilalla kannattavuutta voitaisiin parantaa tekemällä osa metsänhoitotöistä omatoimisesti ostopalvelun sijasta. Metsätalouden kannattavuuslaskurin todettiin soveltuvan kannattavuuden tarkasteluun tilatasolla. Metsätalouslaskurin edellyttämä metsäsuunnitelma mahdollistaa mahdollisimman luotettavan kannattavuuden arvioinnin. Epävarmuustekijöinä laskelmissa on rahavirtojen perustuminen pitkän ajan indekseihin. Motti-ohjelmisto soveltuu erilaisten metsänkäsittelyvaihtoehtojen vertailuun ja niistä aiheutuvien kustannusten arviointiin kuviotasolla. Motti-ohjelman epävarmuustekijänä on puuttuva mahdollisuus simuloida luonnon tai ihmisten aiheuttamien tuhojen vaikutusta metsikön kasvuun.The purpose of this thesis was to estimate profitability in a certain forest holding using silvicultural softwares and evaluate their suitability for use in forestry. The theory part handles Finnish forest resources and forest ownership structure. The profitability of forest holdings was based on the theory in incomes, expenses and taxes. The material for the thesis was a forest management plan that was made in 2015. The thesis consisted of the evaluation of the profitability in one forest holding using a profitability calculation programme and Motti-software. With the profitability calculation programme a summary of the financial figures, balance sheets, income statements and cash flow developments in forest holdings was done. Motti-software was used to make development predictions in the representative compartments and estimate the economic viability of silvicultural works. The average business result in the forest holding was 10 073 euros per year. The average business result per hectare was 45 euros. The turnover of the forest holdings remained positive in the whole period expect the last year, because there were no fellings according to the forest management plan. The profitability of the forest holdings can be improved by making part of the silvicultural work on your own instead of buying the service. The Profitability calculation programme was suitable for examining the profitability at the forest holding level. Because the software requires a forest management plan, the profitability can be estimated as reliably as possible. The uncertainty in the calculations is based on long term esti-mates in cash flows. Motti-software is suitable for comparing silvicultural works and fellings at a compartment level. Motti-software does not have an option to simulate natural or human damage to the development of a forest stand

The Accuracy of Ankle Eccentric Torque Control Explains Dynamic Postural Control During the Y-Balance Test

# Background The Y-Balance Test (YBT), especially the posteromedial (PM) reach direction (PM-YBT), is able to identify dynamic postural control deficits in those who have ankle instability. However, there still exists a need to understand how sensorimotor function at the ankle explains the performance during the PM-YBT. # Hypothesis/Purpose The purpose of this study was to determine whether the ability to accurately control eccentric ankle torque explained PM-YBT performance. It was hypothesized that eccentric dorsiflexion/plantarflexion torque control would be positively related to the maximum reach distance (MRD) of PM-YBT. # Study Design Cross-sectional study # Methods Twelve healthy subjects performed the PM-YBT, maximum voluntary isometric contractions (MVIC) for both dorsiflexion and plantarflexion muscle strength, and then the torque control testing of the ankle. The torque control testing provided a target torque level on a screen in front of the subject and passive rotations of the ankle joint in the sagittal plane at 10 deg/sec between plantarflexion to dorsiflexion. Subjects were then instructed to eccentrically contract the dorsiflexors and plantar flexors to generate torque while the ankle joint rotated. The accuracy of torque control during eccentric dorsiflexion and plantarflexion by calculating absolute errors, the area between the target torque and the produced torque were evaluated. Tibialis anterior and soleus muscle activities were simultaneously recorded during testing. A step-wise linear regression model was used to determine the best model predicted the MRD of the PM-YBT (PM-MRD). # Results A step-wise linear regression developed a model explaining only eccentric dorsiflexion torque control predicted higher PM-MRD score (R^2^ = 44%, F~1,10~ = 7.94, β = -0.67, p = 0.02). # Conclusion The accuracy of torque control during eccentric dorsiflexion predicts better performance in the PM-YBT. # Level of Evidence 3

Cytosolic Sensors of Viral RNA Are Involved in the Production of Interleukin-6 via Toll-Like Receptor 3 Signaling in Human Glomerular Endothelial Cells

Background/Aims: Dysregulation of interleukin-6 (IL-6) production in residual renal cells may play a pivotal role in the development of glomerulonephritis (GN). Given that Toll-like receptor 3 (TLR3) signaling has been implicated in the pathogenesis of some forms of GN, we examined activated TLR3-mediated IL-6 signaling in cultured normal human glomerular endothelial cells (GECs). Methods: We treated GECs with polyinosinic-polycytidylic acid (poly IC), an authentic double-stranded RNA, and analyzed the expression of IL-6 and the cytosolic viral RNA sensors retinoic acid-inducible gene-I (RIG-I) and melanoma differentiation associated gene 5 (MDA5) using reverse transcription quantitative real-time polymerase chain reaction, western blotting, and enzyme-linked immunosorbent assays. To further elucidate the effects of poly IC on this signaling pathway, we subjected the cells to small interfering RNA (siRNA) against TLR3, interferon (IFN)-β, RIG-I, and MDA5. Results: We found that poly IC induced the expression of RIG-I, MDA5 and IL-6 via TLR3/IFN-β signaling in GECs. siRNA experiments revealed that both MDA5 and RIG-I were involved in the poly IC-induced expression of IL-6, with MDA5 being upstream of RIG-I. Conclusion: Interestingly, cytosolic sensors of viral RNA were found to be involved in IL-6 production via TLR3 signaling in GECs. Regional activation of TLR3/IFN-β/ MDA5/RIG-I/IL-6 axis due to viral and “pseudoviral” infections is involved in innate immunity and inflammatory reactions in GECs. We believe this signaling pathway also plays a pivotal role in the development of some forms of GN

Th17 cells differentiated with mycelial membranes of Candida albicans prevent oral candidiasis

Candida albicans is a human commensal that causes opportunistic infections. Th17 cells provide resistance against mucosal infection with C. albicans; however, the T cell antigens remain little known. Our final goal is to find effective T cell antigens of C. albicans that are responsible for immunotherapy against candidiasis. Here, we prepared fractions including cytosol, membrane and cell wall from yeast and mycelial cells. Proteins derived from a membrane fraction of mycelial cells effectively induced differentiation of CD4+ T cells into IL-17A-producing Th17 cells. To confirm the immunological response in vivo of proteins from mycelial membrane, we performed adoptive transfer experiments using ex vivo stimulated CD4+ T cells from IL-17A-GFP reporter mice. Mycelial membrane-differentiated CD4+ Th17 cells adoptively transferred intravenously prevented oral candidiasis by oral infection of C. albicans, compared with control anti-CD3-stimulated CD4+ T cells. This was confirmed by the clinical score and the number of neutrophils on the infected tissues. These data suggest that effective T cell antigens against candidiasis could be present in the membrane protein fraction of mycelial cells. The design of novel vaccination strategies against candidiasis will be our next step.福岡歯科大学2017年
