    (2014) Keles, Sukru; Gul, Senay; Yildiz, Abdullah; Karabulut, Seyhan Demir; Eren, Handan; Iskender, Mahinur Durmus; Baykara, Zehra Gocmen; Yalim, Neyyire Yasemin; https://orcid.org/0000-0001-5473-573X; 34018435; AAB-3163-2021
    The aim of this study is to discover medical students' ideas on the phenomenon of death; produce information on how these students interpret the value-related problems regarding death that they come across in different units of hospitals; and assess this data in ethical terms. This study included a qualitative research in which 12 focus group interviews were conducted with 92 fifth- and sixth-year medical students. Data obtained from interviews were assessed using a thematic content secondary analysis. The main themes were specified according to the medical students' statements and were reviewed under the contexts of the "dying process"; "effects of death"; "attitude and behavior of health professionals"; "seeing a dead body/looking at a dead body"; "accepting death"; and "forms of expressions of death." Medical students' encounters with death in different units of hospitals leads them to question their values and familiarize themselves with the borders of their areas of profession.

    Goodness-of-fit and Randomness Tests for the Sun's Emissions True Random Number Generator
    (2014) Tanyer, Suleyman Gokhun; Atalay, Kumru Didem; Inam, Sitki Cagdas; 0000-0003-0820-9186; I-5023-2013; JHU-3888-2023
    Random number generators ( RNGs) are one of the key tools necessary for statistical analysis and optimization methods such as Monte Carlo, particle swarm optimization ( PSO) and the genetic algorithm. Various pseudo and true RNGs are available today, and they provide sufficient randomness. Unfortunately, they generate data that do not always represent the required distribution accurately, especially when the data length is small. This could possibly threaten the 'repeatability' of an academic study. A novel true RNG ( TRNG) using the method of uniform sampling ( MUS) is recently proposed. In this work, the Sun's RF emissions MUS-TRNG is comparatively tested with well known pseudo and true RNGs. It is observed that both randomness and very high goodness-of-fit qualities are possible.

    True Random Number Generation of Very High Goodness-of-fit and Randomness Qualities
    (2014) Tanyer, Suleyman Gokhun; I-5023-2013
    The statistical nature of numerous problems in mathematics, physics and engineering have led to the development of methods for generating random data for a given distribution. Ancient methods include; dice, coin flipping and shuffling of cards. Today, various pseudo, quasi and true random generators ( RNGs) are being proposed for their improved properties. In this work, test metrics for goodness-of-fit and randomness are reviewed. The method of uniform sampling ( MUS) is modified for improving the randomness without harming the goodness-of-fit qualities. The test results illustrate that very high goodness-of-fit can be obtained even when the number of observed samples is as small as 10.

    Efficient Recognition of Human Emotional States from Audio Signals
    (2014) Erdem, Ernur Sonat; Sert, Mustafa; https://orcid.org/0000-0002-7056-4245; AAB-8673-2019
    Automatic recognition of human emotional states is an important task for efficient human-machine communication. Most of existing works focus on the recognition of emotional states using audio signals alone, visual signals alone, or both. Here we propose empirical methods for feature extraction and classifier optimization that consider the temporal aspects of audio signals and introduce our framework to efficiently recognize human emotional states from audio signals. The framework is based on the prediction of input audio clips that are described using representative low-level features. In the experiments, seven (7) discrete emotional states (anger, fear, boredom, disgust, happiness, sadness, and neutral) from EmoDB dataset, are recognized and tested based on nineteen (19) audio features (15 standalone, 4 joint) by using the Support Vector Machine (SVM) classifier. Extensive experiments have been conducted to demonstrate the effect of feature extraction and classifier optimization methods to the recognition accuracy of the emotional states. Our experiments show that, feature extraction and classifier optimization procedures lead to significant improvement of over 11% in emotion recognition. As a result, the overall recognition accuracy achieved for seven emotions in the EmoDB dataset is 83.33% compared to the baseline accuracy of 72.22%.

    In Vitro Evaluation of E. coli And S. epidermidis Adhesion on Dressing Materials Used in Hypospadias Repair
    (2014) Soyer, Tutku; Bostanoglu, Ebru; Aslan, Mustafa Kemal; Boybeyi, Ozlem; Demirbilek, Muge; Gocmen, J. Sedef; JWP-3001-2024
    Background An in vitro study was performed to evaluate the adherence of Escherichia coli and Staphylococcus epidermidis to different dressing materials. Methods Hydrophyl gauze swab (GS), sterile flax swab (FS), and their nitrofurazone (Furacin (R)) absorbed forms (GSF and FSF), sterile paraffin-covered gauze with chlorhexidine acetate (0.5 %) (Bactigrass (R), BG), and semipermeable transparent film gauze (Tegaderm (R), TG) were used in the study. A 1 cm(2) of each material was placed in culture plates, and E. coli ATCC 25922 and S. epidermidis ATCC 12228 were suspended in each plate. After 24, 48 h, and 1 week of incubation period, colony counts were calculated in colony-forming units (CFU) per square centimeter unit. Bacterial adhesion was compared between groups, and each dressing material was also compared for different incubation periods (24, 48 h, and 1 week). Results The colony counts were significantly decreased in GSF and FSF groups (Kruskal-Wallis test, p < 0.05). There was no difference for E. coli adhesion in GS, FS, BG, and TG groups (p > 0.05). The significant difference detected for S. epidermidis adhesion in the first 24 to 48 h could not be detected at the end of a 1-week period. There was no statistical difference in groups when compared for 24-, 48-h, and 1-week periods of incubations (Wilcoxon signed-rank test, p > 0.05). In BG group, E. coli adhesion was increased, and S. epidermidis adhesion was decreased without a significant difference at the end of a 1-week period (p > 0.05). Conclusions Nitrofurazone absorbed sterile gauze materials have less bacterial adhesion. In vitro adhesion of E. coli and S. epidermidis did not differ between the 24-h and 1-week period. E. coli adhesion to BG can be increased if the duration of dressing prolonged up to a 1-week period. Level of Evidence: Not ratable.

    (2014) Cicek, Tufan; Erinanc, Hilal; Gonulalan, Umut; Sen, Erhan; Ozturk, Bulent; 0000-0003-1944-1722; 0000-0003-1401-6356; AAJ-8576-2021; AAL-1268-2021
    Prostatic melanosis is characterized by melanocytic proliferation in prostatic stroma and the epithelium. The pathogenesis of the lesion is uncertain. In literature it has been reported as a case associated with prostatic adenocarcinoma before. Primary and metastatic malignant melanoma should be considered in differantial diagnosis of the lesion.

    Disasters As An Ideological Strategy For Governing Neoliberal Urban Transformation in Turkey: Insights from Izmir/Kadifekale
    (2014) Saracoglu, Cenk; https://orcid.org/0000-0002-4797-4879; 24325244; AAJ-4574-2020
    Since the turn of the twenty-first century, Turkish cities have undergone large-scale change through a process referred to as urban transformation, involving, notably, the demolition of inner-city low-income settlements. The official authorities and business circles have resorted to various forms of discourse to justify these projects, which have led to the deportation of a significant number of people to peripheral areas. The discourse of natural disasters', for example, suggests that urban transformation is necessary to protect people from some pending event. Probably the most effective application of this discourse has occurred in Izmir, where the risk posed by landslides' has played a critical role in the settlement demolitions conducted in the huge inner-city neighbourhood of Kadifekale. By examining the case of Kadifekale, this paper provide some insights into how natural disasters' serve as a discourse with which to legitimise the neoliberal logic entrenched in the urban transformation process in Turkey.

    Clinical and Cytologic Features of Antibiotic-Resistant Acute Paronychia
    (2014) Durdu, Murat; Ruocco, Vincenzo; https://orcid.org/0000-0003-1247-3932; 24355264; H-9068-2019
    Background: Acute paronychia usually is treated as a bacterial infection, but antibiotic-resistant acute paronychia may be caused by other infectious and noninfectious problems. Objective: We sought to describe the clinical, etiologic, cytologic, and therapeutic features of antibiotic-resistant acute paronychia. Methods: A retrospective review of medical records and cytology was performed in 58 patients (age, 1 month-91 years; 36 children and adolescents [62%] and 22 adults [38%]) who had antibiotic-resistant acute paronychias. Results: Causes of paronychia included bacteria (25 patients [43%]), viruses (21 patients [36%]), fungi (5 patients [9%]), drugs (3 patients [5%]), pemphigus vulgaris (3 patients [5%]), and trauma (1 patient [2%]). Diagnostic cytologic findings were noted in 54 patients (93%); no diagnostic cytologic findings were present with drug-induced (3 patients) or traumatic (1 patient) paronychia. The most common predisposing factors were the habits of finger-or thumb-sucking (14 patients [24%]) and nail-biting (11 patients [19%]). Complications included id reaction with erythema multiforme in 3 patients (5%). Limitations: Limitations include retrospective study design from 1 treatment center. Conclusion: Antibiotic-resistant acute paronychia may be infectious or noninfectious. Cytologic examination with Tzanck smear may be useful diagnostically and may prevent unnecessary use of antibiotics and surgical drainage.
