Rehabilitation of client with Guillain Barré syndrome in occupational therapy - a case study
No full textUvod: Guillain-Barré sindrom je vnetna bolezen perifernega živčevja, ki povzroči hude okvare številnih telesnih funkcij in zgradb, kar omejuje posameznika pri opravljanju vsakodnevnih aktivnosti ali okupacij. Večina bolnikov v nekaj mesecih popolnoma okreva, pri nekaterih pa lahko ostanejo trajne posledice na različnih področjih. Vloga delovnega terapevta pri obravnavi oseb z Guillain-Barré sindromom je vzdrževanje ali izboljšanje spretnosti in funkcij, potrebnih za izvedbo aktivnosti ter priprava na vrnitev v domače okolje. Namen: Namen diplomskega dela je poglobljen prikaz delovnoterapevtske obravnave uporabnika z Guillain-Barré sindromom, vključenega v rehabilitacijo na Univerzitetnem rehabilitacijskem inštitutu Republike Slovenije – Soča ter ugotavljanje učinkovitosti obravnave. Metode dela: Raziskava je bila izvedena v obliki študije primera. V trinajsttedensko delovnoterapevtsko obravnavo je bil vključen 33-letni gospod z Guillain-Barré sindromom. Pri spremljanju napredka smo bili osredotočeni na zastavljene cilje, uporabnikovo dojemanje izvedbe in zadovoljstva z izvedbo njemu pomembnih okupacij, stopnjo samostojnosti pri izvajanju dnevnih aktivnosti ter izboljšanje funkcije rok. Rezultati: Povprečna ocena izvedbe in zadovoljstva z izvedbo se je pri COPM-u izboljšala z 1,2 na 6,4. Analiza aktivnosti je pokazala izboljšanje vseh motoričnih spretnosti. Razlika v skupnem seštevku Lestvice FIM pred in po obravnavi znaša 44 točk, pri vseh zastavljenih ciljih po GAS lestvici je dosegel najboljši možen napredek nad pričakovanim. Moč stiska desne roke je bila za 1 kg večja od moči stiska leve roke, skupna ocena indeksa funkcije roke pri SHAP se je pri desni roki izboljšala iz 67 na 98, pri levi iz 60 na 97. Ob vrnitvi v domače okolje je bil ponovno izveden COPM, kjer je sprememba v oceni izvedbe in zadovoljstva z izvedbo po 2. ocenjevanju znašala 1,4 točk. Razprava in zaključek: Uporabnik je dosegel zastavljene cilje. Spremljanje napredka je pokazalo na izboljšanje večine opazovanih parametrov, izboljšala se je spretnost rok, manjši napredek pa je opazen pri funkciji rok. Proces delovnoterapevtske obravnave po AOTA se je v študiji primera izkazal kot ustrezen.Introduction: Guillain-Barré syndrome is an inflammatory disease of the peripheral nervous system that causes impairment of several bodily functions and skills and limitis individuals in performing their daily activities or occupations. Most patients recover completely within a few months, but some lasting consequences may remain. The role of the occupational therapist in treating people with Guillain-Barré syndrome is to maintain or increase the skills and functional needs, essential for performing the activities and to prepare patients for returning to their domestic environment. Purpose: The purpose of the diploma work is an in-depth presentation of occupational therapy treatment of a client with Guillain-Barré syndrome involved in rehabilitation at University Rehabilitation Institute Republic of Slovenia – Soča, as well as the effectiveness of treatment. Methods: The research was conducted in the form of a case study. A 33-year-old man with Guillain-Barré syndrome was involved in a thirteen-week occupational therapy treatment (modelled on the American framework of practice). While monitoring the progress we focused on achieving the goals set, the client\u27s perception of the performance and his satisfaction with the performance of important activities, the degree of independence in performing daily activities and improving hand function. Results: The COPM showed the increase of the performance from 1.2 to 6.4the same with satisfaction. The analysis of the activity showed that a progress in most motor skills was achieved. The FIM showed the difference in the total score, which was 44 points. At all the goals set according to the GAS scale he achieved the best possible progress above expectations. The strength of the right hand grip was 1 kg higher than the strength of the left hand grip. The final score of the hand function index in the SHAP changed from 67 to 98 for the right hand, and increased from 60 to 97 for the left one. After the client’s return to his domestic environment the COPM was done again, whereby the change in performance and satisfaction measured 1.4 points. Discussion and conclusion: The client achieved all the set goals. Monitoring of the progress showed improvement in most of the observed parameters. Motor skills improved, while less progress was observed in hand function. The process of occupational therapy treatment based on the AOTA framework proved to be appropriate to the case study
The influence of bisphenols on the growth of algae Chlorella vulgaris and establishing cocultures with bacteria to increase algae biomass
No full textUvod: Bisfenoli se ob razgradnji plastičnih proizvodov sproščajo v odpadno vodo, zato je učinkovito čiščenje odpadne vode ključno za zmanjšanje emisij bisfenolov v okolje. Alternativa konvencionalnim biološkim čistilnim napravam so algne tehnologije, ki podpirajo sonaravni trajnostni razvoj in imajo sposobnost odstranjevanja različnih onesnaževal iz odpadne vode. Namen: Želeli smo ugotoviti vpliv mešanice bisfenolov na rast Chlorelle vulgaris v avtotrofnih in miksotrofnih pogojih, učinkovitost odstranjevanja bisfenolov z algami v monokulturi in kokulturi z bakterijami ter z vzpostavljanjem kokultur povečati biomaso alg, da bi dosegli večjo učinkovitost odstranjevanja bisfenolov iz vodnega medija. Metode dela: Poskuse smo izvajali v laboratorijskih algnih bioreaktorjih. Rast mikroalg smo vrednotili na podlagi sprememb koncentracije klorofila a, ki smo ga ekstrahirali iz algnih celic. Bakterije smo osamili iz aktivnega blata čistilne naprave Ajdovščina in algnega bazena z metodo cik-cak razmazov vzorcev na trdnih gojiščih. Vzpostavili smo kokulture z različnimi razmerji med številom celic alg in bakterij. Analizo učinkovitosti odstranjevanja bisfenolov s plinsko kromatografijo z masno spektrometrijo je za nas izvajal Inštitut Jožef Stefan. V poskusih smo uporabili mešanico 17 bisfenolov, koncentracija vsakega je bila 1 µg/L. Rezultati: Bisfenoli niso imeli statistično značilnega vpliva na tvorbo klorofila a v celicah mikroalg. C. vulgaris v kokulturah z bakterijami ni dosegla višjih koncentracij klorofila a kot v monokulturi. Na hitrost rasti alg v kokulturah je najverjetneje vplivala glukoza v rastnem mediju (miksotrofni metabolizem) in ne pozitiven vpliv bakterij. Statistično značilne razlike v učinkovitosti odstranjevanja bisfenolov med različnimi načini kultivacije C. vulgaris smo opazili pri 9 bisfenolih. Pri teh so bile večinoma najbolj učinkovite mikroalge v monokulturi v miksotrofnih pogojih. Učinkovitost odstranjevanja bisfenolov z algami je bila bolj povezana z vrednostjo logKow posameznih bisfenolov kot z načinom gojenja alg (tj. monokultura, kokultura, tip metabolizma). Razprava in zaključek: Rezultati kažejo, da bisfenoli v koncentracijah, značilnih za komunalno odpadno vodo, ne inhibirajo rasti C. vulgaris in da imajo mikroalge potencial za čiščenje bisfenolov iz vodnega medija. V tem se kaže relevantnost te raziskave, zato bi jo v prihodnje lahko razširili v obsežnejšo aplikativno raziskavo.Introduction: Bisphenols are released into wastewater during decomposition of plastic products, therefore effective wastewater treatment is the key to reducing bisphenol emissions into the environment. An alternative to conventional biological treatment plants are algae technologies, which support sustainable development and have the ability to remove various pollutants from wastewater. Purpose: We wanted to determine the effect of a bisphenol mixture on Chlorella vulgaris growth under autotrophic and mixotrophic conditions, as well as the efficiency of bisphenol removal by algae in monoculture and coculture with bacteria. We also wanted to increase algal biomass by establishing cocultures with bacteria and achieve greater efficiency of bisphenol removal from the aqueous medium. Methods: The experiments were conducted in laboratory algal bioreactors. The growth of microalgae was evaluated on the basis of changes in the concentration of chlorophyll a, which was extracted from algal cells. Bacteria were isolated from the activated sludge of the wastewater treatment plant Ajdovščina and the algal pond using the method of smearing the samples in a zig-zag pattern on solid agar. We established cocultures with different ratios of algal and bacterial cell counts. The analysis of the efficiency of bisphenol removal by gas chromatography–mass spectrometry was carried out for us by the Jožef Stefan Institute. A mixture of 17 bisphenols was used in the experiments, the concentration of each being 1 µg/L. Results: There was no statistically significant effect of bisphenols on chlorophyll a formation in microalgae cells. C. vulgaris did not achieve higher chlorophill a concentrations in coculture with bacteria comparing to monoculture. The growth rate of algae in cocultures was most likely influenced by glucose in the growth medium (mixotrophic metabolism) rather than the positive influence of bacteria. Statistically significant differences in bisphenol removal efficiency between different C. vulgaris cultivation methods were noticed in 9 bisphenols. Among these, microalgae were the most effective in monoculture under mixotrophic conditions. The efficiency of bisphenol removal by algae was more related to the logKow value of individual bisphenols than to the method of algal cultivation (i.e. monoculture, coculture, type of metabolism). Discussion and conclusion: The results show that bisphenols do not inhibit the growth of C. vulgaris at concentrations typical of municipal wastewater and that microalgae have the potential to remove bisphenols from the aqueous medium. This shows the relevance of this research, so it could be extended to applied research in the future
Children\u27s workshops about pile dwellers for the permanent exhibition Moja Ljubljanica
No full textMagistrsko delo obravnava tematiko postavitve didaktičnih delavnic za stalno razstavo Moja Ljubljanica na Vrhniki. Delavnice so namenjene šolskim skupinam, in sicer učencem 4. in 6. razreda osnovne šole. V teoretičnem delu smo izpostavili prednosti izkustvenega učenja, uporabo le-tega v muzejih, \u27\u27hands on\u27\u27 princip in načrtovanje izkustvenih in didaktičnih delavnic, katerih cilji se povezujejo z učnima načrtoma za Družbo in Zgodovino v 2. triletju, a se hkrati izvajajo izven šolskega okolja, in sicer v muzejih. Izpostavili smo dosedanje raziskave in ugotovitve na tem področju, predstavili načela izkustvenega učenja in primere dobre prakse. Podali smo izbor literature, ki je povezana s koliščarsko kulturo v evropskem prostoru. Načrtovali smo didaktične delavnice, ki smo jih v doživljajskem razstavišču Moja Ljubljanica tudi izvedli in evalvirali.
V empiričnem delu smo s pomočjo anketnega vprašalnika ugotavljali, kako kakovost delavnic ocenjujejo udeleženi učenci, učitelji in strokovni delavci. Za raziskavo smo uporabili neslučajnostni namenski vzorec, ki je zajemal 89 učencev iz 4. in 6. razreda, iz dveh izbranih slovenskih osnovnih šol (iz območja Ljubljanskega barja) in 5 učiteljev razrednega ali predmetnega pouka, ki poučujejo v 2. triletju, v 4. ali 6. razredu ter 5 strokovnih delavcev/sodelavcev doživljajskega razstavišča Moja Ljubljanica. Uporabili smo kvantitativni raziskovalni pristop. Raziskava bo pomembno pripomogla k načrtovanju didaktičnih delavnic za šolske skupine v doživljajskem razstavišču Moja Ljubljanica in hkrati omogočila izmenjavo znanj med različnimi profili (učitelji razrednega pouka, muzealci, kustosi, arheologi). Istočasno bo omogočila vpogled v možnosti sodelovanja šolskega kadra, razrednih učiteljic s strokovnimi delavci (muzealci, kustosi in arheologi) v muzejih.This master thesis considers the theme of planning didactical workshops for permanent exhibition Moja Ljubljanica in Vrhnika. Workshops are planned for school groups of pupils from 4th to 6th grade. Theoretical part of the thesis presents advantages of experiential learning, use of this kind of learning in museums, a “hands on” principle, planning of experiential and didactical workshops, for which goals are found in Curriculums for Social sciences and History in the second triad but are also being carried out outside the school – in museums. We pointed out existing research and findings on this matter, we presented principles of experiential learning and examples of good practice. An overview of literature, concerning pile dwellers culture in the European area, was also done. We planned didactical workshops, performed them at an experimental exhibition stand Moja Ljubljanica and evaluated them.
In the empirical part we used a questionnaire to find out how pupils, who were involved in workshops, teachers and professional workers evaluate quality of the workshops. For this research we used non-probability purposive sample, which included 89 students from 4th and 6th grade from two Slovenian primary schools (area of Ljubljansko barje), 5 primary education teachers or teachers for specific subjects, who teach in the second triad – 4th and 6th grade, and 5 professional workers/co-workers from the experimental exhibition stand Moja Ljubljanica. This was done using quantitative research. The research will significantly add to planning of didactical workshops for school groups at experimental exhibition stand Moja Ljubljanica and at the same time also enable the exchange of knowledge between different profiles (teachers of primary education, museum workers, curators, archaeologists). It also offers an insight into the possibility of cooperation between school – primary education teachers and professional workers (museum workers, curators, archaeologists) in museums
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
