Computed tomography assessment of temporomandibular joint position and dimensions in patients with class II division 1 and division 2 malocclusions

This study aimed to investigate and compare the positions and dimensions of the temporomandibular joint and its components, respectively, in patients with Class II division 1 and division 2 malocclusions. Computed tomography images of 14 patients with Class II division 1 and 14 patients with Class II division 2 malocclusion were included with a mean age of 11.4 ± 1.2 years. The following temporomandibular joint measurements were made with OsiriX medical imaging software program. From the sagittal images, the anterior, superior, and posterior joint spaces and the mandibular fossa depths were measured. From the axial images, the greatest anteroposterior and mediolateral diameters of the mandibular condyles, angles between the long axis of the mandibular condyle and midsagittal plane, and vertical distances from the geometric centers of the condyles to midsagittal plane were measured. The independent samples t-test was used for comparing the measurements between the two sides and between the Class II division 1 and 2 groups. No statistically significant differences were observed between the right and left temporomandibular joints; therefore, the data were pooled. There were statistically significant differences between the Class II division 1 and 2 groups with regard to mandibular fossa depth and anterior joint space measurements. In Class II patients, the right and left temporomandibular joints were symmetrical. In the Class II division 1 group, the anterior joint space was wider than that in Class II division 2 group, and the mandibular fossa was deeper and wider in the Class II division 1 group

Multimission Aircraft Design Study-Operational Scenarios

In the most recent years, the Command, Control and Communications, Counter Measures, Intelligence, Surveillance and Reconnaissance (C3CMISR) aircrafts are used commonly in many NATO and UN Operations around the world. These aircrafts are AWACS, JSTARS, Rivet Joint, Compass Call and ABCCC. They provide close air support in the name of airborne surveillance, ground moving target surveillance, target reconnaissance, jamming, and command, control and communications issues in operational environments. Those aircrafts are tasked with a wide variety of missions than ever before in operational theaters and each one of them comprises a specific amount of cost and risk factors. As a new vision, while replacing the existing legacy systems, multi-mission architectures are taken into consideration for the C3CMISR missions. The stated objective is designing a one tail number Multi-Mission Aircraft (MMA) that includes all the C3CMISR tasks on one airframe. This study seeks some comments and advises about the MMA design technical feasibility. In order to search for these comments, four notional operational scenarios are created. First of all existing C3CMISR aircrafts are considered and evaluated in these operational scenarios and then different MMA architectures are defined and compared with the legacy systems in the name of adequacy

Perceptions of Audience on Soundpainting Performance

Today, contemporary music emerges as an experimental phenomenon trapped in the laboratory environment rather than an element of skill. Modern music, where principles such as specialism and rationality are determinative, has become difficult to understand not only for performers who carry it on the stage but also for today's audience. One of the works done in recent years is Soundpainting, which is based on improvisation and allows everyone to do this stage art. Soundpainting is the multidisciplinary live composing sign language for Musicians, Dancers, Actors and Visual Artists. Presently the language comprises more than 1750 gestures that are signed by the Soundpainter to indicate the type of material desired of the performers. The Soundpainter (the composer) standing in front (usually) of the group communicates a series of signs using hand and body gestures indicating specific and/or aleatoric material to be performed by the group. The Soundpainter develops the responses of the performers, molding and shaping them into the composition. In this research, it is aimed to determine the perceptions of the audiences who are listeners in a Soundpainting performance and at the same time performers in Soundpainting performance. The specify of this perception is important in terms of determine the attitude of the listeners fort he first time involved in the Soundpainting performance as well as bringing solutions to the problem of music and alienation from a different point of view

El uso del suelo/cambio en la cobertura del suelo como un factor importante de la inflamabilidad del paisaje actual en la región del Mediterráneo oriental: un estudio de caso en el suroeste de Turquía

Land use/land cover (LULC) change has been one of the main drivers of landscape changes in the Mediterranean region where there has been an increase in the forested lands. LULC change in the region has not only changed forest stand structure and composition but also resulted in increase in the available combustible fuels. There have been few studies on fuel accumulation in relation to LULC, however, no study explaining quantitatively the relationship between LULC change and canopy fuel load in the Mediterranean region. The objective of this study is to evaluate the effects of LULC changes on overall crown fire hazard through examining stand structure, composition, and canopy fuel loads in Eastern Mediterranean forests for 35 years. Forest stand type maps generated from the stereo interpretation of aerial photographs and field survey data were used for the analyses. The results of the study showed significant changes in LULC during the period of 1977-2012. There was a 16.6 % decrease in agricultural areas, 144.5 % increase in settlement areas and 6.8 % increase in pine forests. As for the structural and compositional changes in forested lands, open pine stands that included Mediterranean shrub communities decreased (77.2 %); nonetheless, closed pure pine stands increased (49.9 %), resulting in an increase in the total canopy fuel load in pine stands (86.4 %). Results indicated that landscapes tended to become more homogeneous, fully closed pine stands, resulting in an increase in the continuity and the buildup of fuels available for combustion.El cambio en el uso del suelo/cobertura del suelo (LULC) ha sido uno de los principales impulsores de los cambios en el paisaje en la región mediterránea, donde ha habido un aumento de las tierras forestales. El cambio de LULC en la región no solo ha cambiado la estructura y composición de los rodales forestales, sino que también ha resultado en un aumento de los combustibles disponibles. Ha habido pocos estudios sobre la acumulación de combustible en relación con LULC, sin embargo, ningún estudio explica cuantitativamente la relación entre el cambio de LULC y la carga de combustible del dosel en la región mediterránea. El objetivo de este estudio es evaluar los efectos de los cambios de LULC en el riesgo general de incendios de copas mediante el examen de la estructura, la composición y las cargas de combustible del dosel de los rodales en los bosques del Mediterráneo oriental durante 35 años. Para los análisis se utilizaron mapas de tipos de masas forestales generados a partir de la interpretación estereoscópica de fotografías aéreas y datos de estudios de campo. Los resultados del estudio mostraron cambios significativos en LULC durante el período 1977- 2012. Hubo una disminución del 16,6 % en las áreas agrícolas, un aumento del 144,5 % en las áreas de asentamiento y un aumento del 6,8 % en los bosques de pino. En cuanto a los cambios estructurales y composicionales de los terrenos forestales, disminuyeron los rodales abiertos de pino que incluían comunidades de matorral mediterráneo (77,2 %), pero aumentaron los rodales cerrados de pino puro (49,9 %), lo que se tradujo en un aumento de la carga total de combustible del dosel en los rodales de pino (86,4 %). Los resultados indicaron que los paisajes tendían a volverse más homogéneos, pinares completamente cerrados, lo que resultó en un aumento en la continuidad y la acumulación de combustibles disponibles para la combustión

The Attitudes of High School Students Studying in Sports High Schools in Turkey toward Addictive Substances

The aim of this study is to reveal the attitudes of students, who study in sports high schools in Turkey, toward addictive substances. The study group consisted of 326 randomly selected students from Elazig, Erzincan and Malatya Sports High Schools. In order to obtain the data from the research group, the Attitude toward Addictive Substances Scale, consisting of 45 items, was used. The data obtained from 326 students were analyzed in SPSS 22 Package software. Firstly, normality analysis was performed and it was decided to perform parametric and non-parametric tests according to the results. There was a statistically significant difference in age and class variables of the students. There was no statistically significant difference between the variables of gender, monthly income of the family and educational status of the parents. As a result of the study, it was observed that male and female students' attitudes toward addiction increased as age and class levels progressed. In this context, more attention should be paid to education-oriented studies to prevent addiction. It is suggested that educational activities, such as psychological support and health programs, provided by guidance teachers and psychological counselors should be increased in number

Citizen-Consumers Wanted: Revitalizing the American Dream in the Face of Economic Recessions, 1981-2012

This article brings sociological theory of governmentality to bear on a longitudinal analysis of American presidential speeches to theorize the formation of the citizen-consumer subject. The 40-year historical analysis which expands through four economic recessions and the presidential terms of Ronald Reagan, William J. Clinton, George W. Bush, and Barack Hussein Obama, illustrates the ways in which the national mythology of American Dream myth has been linked to the political ideology of the state to create the citizen-consumer subject in the United States. The quantitative and qualitative analysis of the data demonstrates first, the consistent emphasis on responsibility as a key moral value albeit meshed with ideals of liberalism and libertarianism at different presidential periods; second, the presidents iteratively link the neoliberal political ideology and the national myth of American dream through a sophisticated morality play myth, where they cast the citizen-consumer as a responsible moral hero on a journey to achieve American dream, and, third, the presidents use three main dispositives – disciplinary, legal and security - to craft the citizen-consumer subject in their response to the economic recessions. The findings extend prior consumer research on consumer subjectivity, consumer moralism, marketplace mythology and politics of consumption

The Status Costs Of Subordinate Cultural Capital: At-Home Fathers\u27 Collective Pursuit Of Cultural Legitimacy Through Capitalizing Consumption Practices

Consumer researchers have primarily conceptualized cultural capital either as an endowed stock of resources that tend to reproduce socioeconomic hierarchies among consumer collectivities or as constellations of knowledge and skill that consumers acquire by making identity investments in a given consumption field. These studies, however, have given scant attention to the theoretical distinction between dominant and subordinate forms of cultural capital, with the latter affording comparatively lower conversion rates for economic, social, and symbolic capital. To redress this oversight, this article presents a multimethod investigation of middle-class men who are performing the emergent gender role of at-home fatherhood. Our analysis profiles and theoretically elaborates upon a set of capitalizing consumption practices through which at-home fathers seek to enhance the conversion rates of their acquisitions of domesticated (and subordinate) cultural capital and to build greater cultural legitimacy for their marginalized gender identity

The Role of Partial Nephrectomy without Arterial Embolization in Giant Renal Angiomyolipoma

Angiomyolipoma is a benign neoplasm composed of varying admixtures of blood vessels, smooth muscle cells, and adipose tissue. Because of an increased risk of spontaneous haemorrhage, surgical approach is needed greater than 4–8 cm size. We here report our partial nephrectomy experience in the 24 cm size giant angiomyolipoma. 26-year-old woman referred to our clinic with a 24 cm size angiomyolipoma in her lower pole of right kidney. The inferior vena cava was deviated to the left by the mass. All the blood tests were normal and we offered her the choices of partial nephrectomy or nephrectomy. Right subcostal approach was used. The patient underwent resection of the mass with a safety region of 1 cm. Frozen section evaluation was consistent with angiomyolipoma and free for surgical margin. Warm ischemia time was 35 min. and intraoperative bleeding volume was 200 cc. Postoperative 2nd day the drain was taken and hospital stay was 4 days. In literature we observed very rare angiomyolipoma cases with such a large dimension treated by partial nephrectomy without arterial embolization. If technically suitable partial nephrectomy is the main chioce in this kind of benign lesions in young patients
