To obtain the image, the magnetic resonance was used, specifically spin echo sequence. Further work is focused on digital image processing in order to obtain the necessary image information. The algorithm of linear mask operator was applied for reducing of noise and segmentation of image by thresholding was performed. Geometric properties of examined objects were obtained by integrated functions in MATLAB.

My Failure With An Ojibwe Artist: Reflections On Initial Intercultural Relationships

In this article, I examine a first meeting with Ojibwe artist, Terry Kemper, during which I failed to initiate our meeting with the gift of tobacco. I explore failure in a relational event with Kemper and discuss the intentions of my ethnographic research, my researcher-identity, and my mistake of initially neglecting Ojibwe protocol during my first meeting with the artist, in addition to the role of tobacco in Ojibwe communities. Through aesthetic inquiry I reframe failure in an installation entitled, Toward Reconciliation” that has potential pedagogical implications, with hope that it avoids a static and impotent result. I intend the article and installation as a public engagement of my continued apology and hope for continued conversation with Kemper to reflect and revisit ongoing ethically and culturally appropriate relationships

Kinesiological leisure activities of pupils of the Našice county

Život u dobu procvata tehnologije donosi mnoge prednosti, ali i nedostatke. Zbog sedentarnog načina života ljudsko tijelo zahvatilo je niz bolesti. Oni koji će najviše patiti su djeca i mladi koji su u procesu mentalnog i tjelesnog rasta i razvoja. Nedovoljno kretanje djece i mladih negativno utječe na antroploški sustav i zdravlje općenito. Brojna istraživanja ukazuju da je tjelesna aktivnost jedan od glavnih sredstava u borbi za zdrav i kvalitetan život. Današnja djeca često svoje slobodno vrijeme provode pred televizijom, računalom ili mobitelom. Jedan od razloga je neprisutnost roditelja radi poslovnih obveza. Cilj ovog diplomskog rada bio je otkriti koliko su učenici tjelesno angažirani, kojim se aktivnostima bave u slobodno vrijeme, zašto te kakvi su im stavovi prema tjelesnoj i zdravstvenoj kulturi. Za potrebe istraživanja uključen je uzorak od 91 učenika, trećih i četvrtih razreda osnovnih škola Našičke regije. Ukupni broj učenika podijeljen je na dva subuzorka, u prvom je njih 33 iz grada Našica (15 učenika i 18 učenica), a u drugi subuzorak činilo je 58 učenika (27 učenika i 31 učenica) iz dva ruralna područja u okolici Našica. Rezultati istraživanja pokazali su kako su učenici trećih i četvrtih razreda zadovoljavajuće tjelesno angažirani. Očaravajući je podatak da se više od 90% učenika bave tjelesnom aktivnošću ili sportom te nisu uočene razlike s obzirom na mjesto stanovanja. Najčešće se u svoje slobodno vrijeme bave sportom od čega se izdvaja nogomet, rolanje, trčanje i tenis. I jedan i drugi subuzorak slobodno vrijeme provodi pred televizijom ili računalom 1, 2 sata dnevno. Urbana sredina najčešće se bavi tjelesnom aktivnošću ili sportom zbog zabave i zdravlja, dok se ruralna sredina izjasnila da je razlog zdravlje i druženje s prijateljima. Bitan podatak govori kako se većina učenika urbane i ruralne sredine bavi tjelesnom aktivnošću svaki dan ili 2-3 puta tjedno. Od iznimne je važnosti i učenička svijest o važnosti tjelesne aktivnosti koju smatra više od 80% učenika bez uočenih razlika s obzirom na mjesto stanovanja. Stavovi prema tjelesnoj i zdravstvenoj kulturi su pozitivni . Većina učenika smatra da imaju premalo sati tjelesne i zdravstvene kulture te da bi tjelesna i zdravstvena kultura trebala biti svaki dan. Kao najčešću aktivnost koju bi htjeli da se odvija u školi naveli su nogomet. Od ostalih aktivnosti, učenici urbane sredine češće navode odbojku i tenis, za razliku od učenika ruralne sredine koji navode plivanje i taekwondo.Life in the era of technology boom brings many advantages but also, disadvantages. Because of the sedentary lifestyle, the human body got infected with a number of diseases. Those who will suffer the most are children and young people who are in the process of mental and physical growth and development. Not enough of the physical movement of children and adolescents negatively affects the anthropological system and health in general. Numerous studies indicate that physical activity is one of the main factors in fighting for a healthy and quality life. Today's children often spend their free time in front of a television, computer or mobile phone. One of the reasons is the absence of parents do to business obligations. The aim of this thesis was to find out how much the students are physically engaged, what they are doing in their free time, why are they doing that and what are their attitudes towards physical and health culture. For the research, a sample of 91 students is identified, both in Grade 3 and in Grade 4 of elementary schools in the region of Našice. The total number of pupils was divided into two sub-classes, in the first one 33 students from Našice (15 male and 18 female) and 58 students (27 male and 31 female) from two rural areas around Našice. The results of the research showed that physical engagement of pupils in Grade 3 and in Grade 4 is satisfactory. It is fascinating that more than 90% of students are engaged in physical activities or sports and there are no differences with respect to their place of residence. Most often, they spend their free time playing sports out of which football, roller-skating, running and tennis stand out. Both samples of students are spending their free time watching television or using a computer between one and two hours a day. The students in urban areas are mostly engaged in physical activities or sports for entertainment and health, whereas the pupils in rural areas said that the reason for physical activities is because of health and socializing with friends. Essential data suggests that most of the urban and rural students are engaged in physical activities every day or 2-3 times a week. Of great importance is the student's awareness of the importance of physical activity, which is known by more than 80% of the students without any observed differences with regard to the place of residence. Attitudes toward Physical education are positive. Most students consider that they don’t have enough hours dedicated to Physical education and that is should be present in everyday life in school. Soccer is considered to be one of the activities pupils would like to present in school lessons. Out of other activities, urban students most often mention volleyball and tennis, as opposed to rural students who mention swim and taekwondo

Graduate Recital, Trumpet

My concept for this recital was to pay tribute to the trumpet lineage of Art Blakey and the Jazz Messengers. I owe a great deal to Blakey, as some of the trumpeters in this group are my biggest influences. Lee Morgan made such an impact on Bobby Timmons\u27 Moanin that future Messengers horn players would quote the beginning and ending of Lee\u27s solo. This tune became synonymous with the Jazz Messengers. Horace Silver\u27s composition Nica\u27s Dream was recorded on an album featuring trumpeter Donald Byrd. The beautiful Jerome Kern and Otto Harbach ballad Yesterdays was a personal favorite of Kenny Dorham. When Freddie Hubbard first heard Clare Fischer\u27s Pensativa he said he couldn\u27t get the melody out of his head and arranged it for the Messengers. Trumpeter Terence Blanchard\u27s composition Oh By The Way became a staple of the group\u27s repertoire. I composed The Jester and Das Dat in the hard bop style of the Jazz Messengers

Methodological Considerations for Intercultural Arts Research: Phenomenology, Ethnography, Collage Narrative, and Ethics

Living and working with Ojibwe participants in northern Minnesota informed a phenomenological approach to my three-month multi-sited ethnography. This research encompassed aspects of oral history and arts inquiry to investigate artistic processes, personal histories, and community relations of Ojibwe participants. I sought situational meaning generated between Ojibwe participants and my varied roles as an arts researcher, apprenticing artist, laborer, house caretaker, student and friend in order to articulate relational understandings of arts-mediated experiences. These experiences generated narrative content as collage and continuously directed the flow of the study, shifted my inquiry process, smudged my positionalities, and carefully informed my reflexive research ethics

Missiles in the White City : how governments creatively destroyed Chicago's Jackson Park three times in 80 years

Jackson Park, located on Chicago's South Side, has been a touchstone for the city's residents since the 1890s. The park has a rich history: The site of the 1893 World's Columbian Exposition, an island of green in the city and as an anti-aircraft missile base. But those changes have come at the behest of governments and the park's role has changed as the priorities and values of those governments have evolved. This thesis examined the change in landscape through the lens of the economic theory of creative destruction, which had only been applied to entrepreneurial landscape changes previously. It applied a three-step test to determine whether or not creative destruction could be applied to government-driven landscape changes
