Unsupervised learning to cluster the disease stages in parkinson's disease

Parkinson's disease (PD) is the second most common neurodegenerative disorder (after Alzheimer's disease) and directly affects upto 5 million people worldwide. The stages (Hoehn and Yaar) of disease has been predicted by many methods which will be helpful for the doctors to give the dosage according to it. So these methods were brought up based on the data set which includes about seventy patients at nine clinics in Sweden. The purpose of the work is to analyze unsupervised technique with supervised neural network techniques in order to make sure the collected data sets are reliable to make decisions. The data which is available was preprocessed before calculating the features of it. One of the complex and efficient feature called wavelets has been calculated to present the data set to the network. The dimension of the final feature set has been reduced using principle component analysis. For unsupervised learning k-means gives the closer result around 76% while comparing with supervised techniques. Back propagation and J4 has been used as supervised model to classify the stages of Parkinson's disease where back propagation gives the variance percentage of 76-82%. The results of both these models have been analyzed. This proves that the data which are collected are reliable to predict the disease stages in Parkinson's disease.

Manoeuvring between anxiety and control : Patients experience of learning to live with diabetes: a lifeworld phenomenological study

Research shows that people with diabetes want their lives to proceed as normally as possible, but some patients experience difficulty in reaching their desired goals with treatment. The learning process is a complex phenomenon interwoven into every facet of life. Patients and healthcare providers often have different perspectives in care which gives different expectations on what the patients need to learn and cope with. The aim of this study, therefore, is to describe the experience of learning to live with diabetes. Interviews were conducted with 12 patients afflicted with type 1 or type 2 diabetes. The interviews were then analysed with reference to the reflective lifeworld research approach. The analysis shows that when the afflicted realize that their bodies undergo changes and that blood sugar levels are not always balanced as earlier in life, they can adjust to their new conditions early. The afflicted must take responsibility for balancing their blood sugar levels and incorporating the illness into their lives. Achieving such goals necessitates knowledge. The search for knowledge and sensitivity to changes are constant requirements for people with diabetes. Learning is driven by the tension caused by the need for and dependence on safe blood sugar control, the fear of losing such control, and the fear of future complications. The most important responsibilities for these patients are aspiring to understand their bodies as lived bodies, ensuring safety and security, and acquiring the knowledge essential to making conscious choices.

Patients' experiences of support for learning to live with diabetes to promote health and well-being : A lifeworld phenomenological study

Learning to live with diabetes in such a way that the new conditions will be a normal and natural part of life imposes requirements on the person living with diabetes. Previous studies have shown that there is no clear picture of what and how the learning that would allow persons to incorporate the illness into their everyday life will be supported. The aim of this study is to describe the phenomenon of support for learning to live with diabetes to promote health and well-being, from the patient's perspective. Data were collected by interviews with patients living with type 1 or type 2 diabetes. The interviews were analysed using a reflective lifeworld approach. The results show that reflection plays a central role for patients with diabetes in achieving a new understanding of the health process, and awareness of their own responsibility was found to be the key factor for such a reflection. The constituents are responsibility creating curiosity and willpower, openness enabling support, technology verifying bodily feelings, a permissive climate providing for participation and exchanging experiences with others. The study concludes that the challenge for caregivers is to create interactions in an open learning climate that initiates and supports reflection to promote health and well-being.

ICT as a tool in English teaching : A literature review on the use of ICT for Swedish students with learning difficulties and their literacy learning in grades 7-9

Information and communication technology (ICT) is a subject that is being discussed as a tool that is used within education around the world. Furthermore it can be seen as a tool for teachers to individualize students´ education. Students with literacy difficulties, such as dyslexia, are in constant need of new ways to learn, and new ways to be motivated to learn. The aim of this study is to see what research says in regard to how ICT can be used as a tool to help students with literacy difficulties. Literacy difficulties can be due to a number of things, such as the student has not been taught how to read, trouble within the family which can cause distress, or a neurological disorder such as dyslexia. Furthermore, the main research questions will focus on how ICT can be compared to traditional education forms, such as books and a more teacher centered education within the classroom, and whether ICT can be preferred. The results of this literature review indicates that ICT can be seen as a way for teachers to help students with literacy difficulties gain more self-esteem – something the literature tells us students with learning difficulties lack. The results also show how ICT can lead to a more individualized education. This is due to tools that increase reading comprehension and tools that give direct response when working with ICT, which helps students work more independently.

Making Learning Possible : Nätbaserad utbildning vid Högskolan Dalarna

Högskolan Dalarna (HDa) har gjort ett strategiskt/medvetet val genom att betona den pedagogiska utvecklingen för nästa generations lärande (NGL) och har under flera år utvecklat nätbaserade kurser. NGL centrum är ett nav i den pedagogiska utvecklingen på HDa. Vår roll är att möjliggöra studenters lärande. (Ramsden 2003). Vid vår högskola fokuserar vi på olika datorsystem som stödjer lärandet och möjliggör synkron interaktion och kommunikation, både vid seminarier och under föreläsningar. Vi har valt och utvecklat system som stödjer lärandet och kontakten mellan studenter och lärare på ett bra sätt, fokus ligger inte nödvändigtvis på den nyaste teknologin. Vi anser att det är viktigt att skapa förutsättningar för sociokulturella miljöer vid nätbaserade utbildingar och därför är seminarier och samtal mycket viktiga i våra utbildningar. (Säljö 2000). Vi har definierat tre huvudbehov för lärandeprocessen och vi har valt system för informationsutbyte (Fronter), Adobe Connect för seminarier och Videochat - vårt egenutvecklade system för föreläsningar. Vi vet sedan många år att föreläsningar hjälper studenterna att förstå litteraturen bättre. Ett LMS (Fronter) är ett sätt att samla information såsom scheman och uppgifter. Där sker diskussioner om innehåll och kursupplägg, inlämningar, nyheter och meddelanden. När det gäller föreläsningar har vi valt att använda ”live-streaming” med möjlighet att spela in föreläsningen. Vi betraktar varken Adobe Connect eller vår Videochat som virtuella verktyg. De möten som genomförs med dessa verktyg är på riktigt. Studenter och lärare vittnar ofta om att de interagerar mer i ett seminarium via Connect än vad som sker i en fysisk föreläsningssal och bekräftar den pedagogiska närheten. HDa har system som är säkra men vi tror samtidigt på öppenhet och lättillgänglighet. Vi välkomnar gäster in i systemen för att skapa transparens. Läraren har möjlighet att låsa mappar i vårt LMS och göra dem både säkra och privata. Vi vill berätta och visa för intresserade konferensdeltagare hur vi på Högskolan Dalarna jobbar generellt med nätbaserade verktyg men också visa på mer specifika lösningar som har uppskattats av våra studenter och lärare.   References Ramsden, Paul (2003).

Making learning possible - Nätbaserad utbildning för funktionsnedsatta studenter

Making learning possible - Nätbaserad utbildning för funktionsnedsatta studenter Högskolan Dalarna har gjort ett strategiskt/medvetet val genom att betona den pedagogiska utvecklingen för nästa generations lärande (NGL) och har under flera år utvecklat nätbaserade kurser.  Detta innebär även att ibland måste anpassa våra system för t.ex. hörselskadade studenter. Högskolan har en lång tradition av teckentolka föreläsningar i sal. Vi har även under en längre tid teckentolkat inspelade föreläsningar. Efter att ha provat olika sätt att spela in dessa har vi nu landat i ett system där originalföreläsningen är till vänster och tar upp c:a 80% av skärmen. Teckentolken syns i de resterande 20% till höger. Eftersom vi använder samma system för teckentolkningen som våra lärare har i studion blir det ”strömlinjeformat” då vi bara behöver hantera ett system och får den automatisering som är inbyggd. När det gäller seminarier använder vi oss av Adobe Connect. Lärarna, teckentolken och studenterna (även de hörselskadade) är i ett rum där läraren visar sina dokument, samtalar med studenterna o.s.v.. Teckentolken och den hörselskadade studenten har ett extra rum i Connect där tolken syns. När studenten ska prata så tecknar studenten och det taltolkas av tolken i Connect-rummet med läraren. För detta har teckentolkarna ett separat rum/studio med två skärmar för att kunna se och höra båda Connect-rummen. Vi rekommenderar studenten att också ha två skärmar. Teoretiskt borde detta även kunna användas för en hörselskadad lärare men det har inte gjorts några försök hos oss. Vi vill visa med ljud och bild för intresserade åhörare hur vi har byggt detta arbete och hur hinder kan överbryggas. References Ramsden, Paul (2003). Learning to teach in higher education. 2. ed.

Skicklig läs- och skrivundervisning i åk 1-3 : Om lärares möjligheter och hinder

This study focuses on teachers’ opportunities and obstacles to perform skillful reading and writing instruction. It’s about the ability to accurately identify where students are in their reading and writing process and to help them develop good reading skills. It is also about the ability to recognize signs of difficulties that students may have in their written language development and to know what efforts are needed to help them advance their reading and writing skills. The research is based on teachers’ own statements and survey responses on the external conditions for teaching and on their approach, attitudes and knowledge in reading and writing. The empirical material consists of interviews, surveys and test data. The interview study was conducted with eight teachers. The questionnaire was answered by 249 teachers, while the knowledge test was conducted of 269 teachers and 31 special education teachers. Many of the teachers in this study have lack knowledge in the structure of language and common Swedish spelling rules. Furthermore, it appears that a large part of them are unaccustomed to explaining, in detail, students’ reading development and find it difficult to systematically describe the aspects of daily literacy instruction. The overall picture is that many teachers teach without having tools to reflect on how their education really affects students’ reading and writing. These shortcomings make it difficult to conduct effective literacy instruction. Once students have learned to decode or if they have reading difficulties, many teachers seem to one-sidedly focus on getting students to read more. The consequence could be that those who would need to practice more on the technical basic of reading or comprehension strategies are left without support. Lack of variety and individuality in fluency and comprehension training can challenge the students’ reading and writing development. The teachers in the study, who have the old junior school teacher and elementary teacher education, have the highest amount of knowledge of reading and writing (the test). Good education can provide student teachers with professional skills that they may develop further in their careers. Knowledge of the meaning of phonological and phonemic awareness as well as knowledge of how to count phonemes seem to be important for knowledge of reading and writing (the test). Knowledge of basic reading processes can be obtained by systematic and structured work with students’ linguistic development, and through continuous dialogues with experienced colleagues on how and why questions. This is one important way to work also in teacher training. When essential professional skills are established in the teacher education, in practice students will obtain the school’s learning goals.

Skolan i livet - livet i skolan : Några illitterata invandrarkvinnor lär sig tala, läsa och skriva på svenska som andraspråk

Many immigrants in Sweden have not had the chance to learn to read and write, for various reasons. In Sweden, literacy is a prerequisite to being able to function in the cultural community, and for many immigrants this is the first time that they experience their inability to read and write as a handicap or see themselves as “illiterate”. The aim of this study is to use a socio-cultural, second language and gender approach to describe, analyse and understand how a number of adult, illiterate, immigrant women experience their situation when they are expected to simultaneously learn to speak, read and write Swedish. The study focuses on two literacy groups in two Swedish municipalities. In one of the groups I act as both teacher and researcher. The thesis is a case study of the learning process of five illiterate immigrant women in Sweden. The results are based on interviews, carried out with the help of an interpreter, and observation of teaching and texts ritten by the students. The study is based on the assumption that human learning is an activity that takes place in a cultural community in a social context. When learning a language, the language is simultaneously the tool that facilitates social communication and the object of the learning process. The study shows that cultural communities influence the women in different ways. Gender structures are firmly planted in a patriarchal value system, which means that women are seen as inferior to men, and women are expected to “meet the demands of others”. The women have no time to study at home, as their household duties are prioritised. However, there are subtle indications that there is a wish to change the situation in accordance with Swedish values and norms. This can be seen in the Swedish for Immigrants (SFI) lessons. As they have little contact with Swedes, school is the only arena in which they have a chance to use Swedish. They are positive towards teaching and school as an institution. Here they are able to develop an alternative identity. The study also shows that teaching in the literacy groups is to a great extent based on a technical approach, in which the teacher tries to elicit a correct answer from the students. Social interaction involving contemplation and negotiation is either not included or not prioritised. the women’s experience and knowledge is not made use of. There are,however, occasions when collaborative discussions take place between the teacher and students. On these occasions an exchange of experiences takes place. Learning is based on the students’ own experiences and thoughts. Linguistic concepts gain meaning in the collaborative discussion. Initially the concepts may be unclear, but the group works on them together, adapting and adjusting them until they finally make sense. Finally, I conclude that women immigrants bring their own socio-cultural values and experience to the school situation, which affects their learning process to varying degrees. Furthermore, immigrant women need more time at school, as it is the only arena in which they can spend time on studying and personal development. another conclusion is that the school must become a learning community that recognises the immigrants’ cultures, makes use of the students’ experience and allows the students to participate in collaborative discussions, so that they can develop their ability to speak, read and write Swedish.
