Aselsan;et al.;Huawei;IEEE Signal Processing Society;IEEE Turkey Section;Netas 26th IEEE Signal Processing and Communications Applications Conference, SIU 2018 -- 2 May 2018 through 5 May 2018 -- -- 137780 In our country, as in the world, domestic animal ownership rate is increasing day by day. Pet owners use a variety of tools and methods to monitor their animals' health. One of the most commonly used methods to track animal health is to observe animal activity level. A decrease in animal's activity level is the first and most obvious symptom in most animal diseases. In this study, an IoT system is developed to automatically recognize and track the activities of domestic animals. The system includes a sensor node attached to the pet's collar, a mobile application that transfers the data collected by this sensor node to the cloud architecture, and a software and user interface that automatically classifies and visualizes data in the cloud architecture. With the obtained data, the pet's activities within a day were determined by showing different classes of action (sitting, walking, running). Dogs were used as subjects in the study. © 2018 IEEE.

Bu araştırma, üniversite öğrencilerinde Covid-19 korkusu ile rekreasyonel akış (flow) yaşantı düzeyleri arasındaki ilişkinin incelenmesi amacıyla gerçekleştirilmiştir. Çalışmada, betimsel nitelikte yer alan ilişkisel tarama modeli kullanılmıştır. Çalışma grubu, Gümüşhane Üniversitesi Beden Eğitimi ve Spor Yüksekokulu’nda eğitim gören 337 öğrenciden oluşmaktadır. Veri toplama aşamasında; ‘‘Flow Yaşantı Ölçeği’’, ‘‘Covid-19 Korkusu Ölçeği’’ ve kişisel bilgi formu kullanılmıştır. Analiz aşamasında, verilerin normal dağılım kriterlerine uygun olduğu tespit edilerek, ikili karşılaştırmalarda Independent Samples T-Test uygulanırken; üç ve daha fazla grup kıyaslamalarında One Way ANOVA testi uygulanmıştır. Üniversite öğrencilerinde Flow Yaşantı Ölçeği ile Covid-19 Korkusu Ölçeği arasındaki ilişki Pearson Korelasyon analizi ile belirlenmiştir. Analiz sonucunda bölüm ve aktif spor durumu değişkenine göre flow yaşantı ölçeği ve Covid-19 korkusu ölçeği puanları arasında anlamlı fark saptanmamıştır. Haftalık katıldıkları etkinlik gün sayısı değişkenine göre Covid-19 korkusu ölçeği ve flow yaşantı ölçek puanları arasında anlamlı farklılık belirlenmiştir. Korelasyon analizi sonucunda, öğrencilerin Covid-19 korku düzeyleri ile flow yaşantısı akış düzeyleri arasında anlamlı ilişki bulunmadığı, Covid-19 korku düzeyleri ile flow yaşantısı kaygı düzeyleri arasında pozitif ve düşük düzeyde anlamlı ilişki olduğu, flow yaşantısı akış düzeyleri ile flow yaşantısı kaygı düzeyleri arasında pozitif ve orta düzeyde anlamlı ilişki olduğu tespit edilmiştir. Bu hususta üniversite öğrencilerinin farklı tür ve alanlardaki rekreasyonel etkinliklere yönelmeleri ve mental destek almalarının faydalı olabileceği öngörülmektedir. This research was carried out to examine the relationship between fear of Covid-19 and recreational flow experience levels in university students. The descriptive relational survey model was used in the study. The study group consists of 337 students studying at Gumushane University School of Physical Education and Sports. During the data collection phase; "Flow Experience Scale", "Covid-19 Fear Scale" and personal information form were used. During the analysis phase, it was determined that the data were in accordance with the normal distribution criteria, and the Independent Samples T-Test was applied in paired comparisons; One Way ANOVA test was applied in comparisons of three or more groups. The relationship between the Flow Experience Scale and the Covid-19 Fear Scale in university students was determined by Pearson Correlation analysis. As a result of the analysis, no significant difference was found between the Flow Experience Scale and Covid19 Fear scale scores according to the department and active sports status variable. A significant difference was determined between the Covid-19 fear scale and flow experience scale scores according to the number of activity days they attended per week. As a result of the correlation analysis, there was no significant relationship between the Covid-19 fear levels of the students and the flow levels of the flow life, there was a positive and low level significant relationship between the Covid-19 fear levels and the anxiety levels of the flow life, and there was a significant relationship between the flow level of the flow experience and the anxiety levels of the flow life. It was determined that there was a positive and moderately significant relationship. In this regard, it is predicted that it may be beneficial for university students to turn to recreational activities in different types and fields and to receive mental support.

Bu araştırmada, Spor Bilimleri Fakültesi öğrencilerinin sosyal ağların kullanım amaçlarının incelenmesi amaçlanmıştır. Çalışmanın evrenini; 2021-2022 eğitim öğretim yılı Marmara Üniversitesi Spor Bilimleri Fakültesi öğrencileri oluştururken, örneklemini; Marmara Üniversitesi Spor Yöneticiliği bölümü öğrencileri oluşturmuştur. Veriler katılımcılara Google Formlar üzerinden ulaştırılmış ve katılımda gönüllülük esas alınmıştır. Toplamda 182 kişiye ulaşılmış olup aykırı uç değerler analizi sonucu 3 form değerlendirmeye alınmamış ve toplamda 179 form değerlendirmeye alınmıştır. Veri toplama aracı olarak, birinci kısımda araştırmacı tarafından oluşturulan kişisel bilgiler, ikinci kısımda Usluel ve ark. (2014) tarafından geliştirilen “Sosyal Ağların Kullanım Amaçları Ölçeği” kullanılmıştır. Bu çalışmada, verilerden elde edilen bulgular çerçevesinde; analiz işlemi SPSS 25.0 paket programı ile yapılmıştır. İkili değişkenler için Mann Whitney U testi, ikiden fazla değişkenler içi Kruskal Wallis H testi yapılmıştır. Ayrıca frekans, yüzde ve güvenirlik katsayısı hesaplamaları yapılmıştır. Analiz yapılırken %95 güven aralığına göre analiz yapılmıştır. Araştırma sonucunda sosyal ağların kullanım amaçları ile yaş değişkeni arasında yapılan analiz sonucu içerik paylaşımı ve eğlence alt boyutları dışında ölçek toplam ve tüm alt değişkenlerde istatistiksel olarak anlamlı farklılık olduğu görülmüştür. Çalışma durumu değişkeni arasında yapılan analiz sonucu sadece işbirliği alt istatistiksel olarak anlamlı farklılık olduğu, sosyal medyada geçirilen süre değişkeni arasında yapılan analiz sonucunda ise iletişim kurma alt boyutunda istatistiksel olarak anlamlı farklılık olduğu görülmüştür (p0.05).

Rüstemli ve Karancı (1997) 1992 Erzincan depremi sonrası yörede yaptıkları araştırmada, afetzedelerin kaygı ve korku düzeyleri ve hayatlarına yön verebileceklerine olan inançlarının olası depremlere karşı hazırlık yapma davranışıyla yakından ilişkili olduğunu ortaya koymuşlardır. Ancak, depremden 4.5 yıl sonra yine aynı bölgede alınan ölçümler, tek başına bu motivasyonun depreme hazırlık yapma davranışını yordamadığını göstermiştir. Öte yandan, yapılan çalışmaların çoğu, depremde yoğun can ve mal kaybına uğramış yörelerde gerçekleşmiştir. Dolayısıyla, bireysel yas reaksiyonlarının bulgulara etkisinin ne düzeyde olduğunu belirlemek zorlaşmaktadır. Bu araştırmanın örneklemi ise, 17 Ağustos depreminden önemli ölçüde etkilenen, ancak birinci derecede zarar gören yerleşim yerleri dışında kalan Bursa ili sınırlarındaki Mudanya ilçesinden seçilmiştir. İlçedeki can ve mal kaybının diğer merkezlere göre çok düşük olması, deprem endişesinin yarattığı korku ve kaygı ile deprem sonucu yaşanılan psikopatolojik problemlerin, bireysel yas reaksiyonlarından bağımsız olarak çalışabilmesine olanak sağlamıştır. In Rüstemli and Karancı’s (1997) study after 1992 Erzincan earthquake, it is revealed that anxiety and fear levels of earthquake victims and their beliefs for being able to direct their own lives is closely related with the behavior of making preparations for probable earthquakes in the future. However, measurements repeated 4.5 years after the earthquake in the same region showed that this motivation alone does not explain the behavior of preparing for the probable earthquakes. However, most of the studies on this issue were done in the regions where a lot of deaths, injuries, and property loss had occured at the earthquakes. Therefore, it is difficult to determine the level of the impact of individual mourning reactions on the results. For the present study, 258 people were interviewed in Mudanya, Bursa. This town was out of the first degree damaged settlement area; yet affected by the earthquake to a high extent. The relatively low degree of the damages by the earthquake in terms of death, injury and property loss made it possible for the researchers to examine the fear, anxiety and psychopathological problems resulting from earthquake experience as independent from individual mourning reactions.

- Abstract
In this report, three patients, admitted to Ankara University Faculty of Medicine, Ibni Sina Hospital, Clinical Bacteriology and Infectious Diseases Department, with the diagnosis of acute viral hepatitis A have been discussed because of their clinical and/or biochemical relapses. Following conservative treatment and bedrest, the liver transaminases decrease to nearly normal levels but a second peak was observed later in three of the cases. Other viral, metabolic and autoimmune factors which could lead to the increase of liver transaminases were ruled out. Anti-HAV IgM antibodies became negative in 2 to 4 months later, and liver enzymes returned to normal in 4 to 5 months after onset of their illnesses. As a result, it was concluded that conservative follow-up and therapy would be sufficient since the prognosis of A hepatitis is usually benign even if it relapsed.

- Abstract
Lung hyperinflation is a consequence of airway obstruction, increased airway resistance and compliance in patients with chronic obstructive pulmonary disease (COPD) which may result in respiratory muscle fatigue and deterioration of gas transfer. The aim of this study was to investigate the influence of hyperinflation on respiratory muscles, gas transfer and breathing pattern and compare the differences between mild and severe COPD. Twenty-eight COPD patients with radiological and tomographic evidence of emphysema were included in the study and they were divided into two groups according to the severity of COPD. Group I= FEV(1) < or = 49% (n= 16). Group II= FEV(1) > or = 50% (n= 12). Airflow rates were decreased and airway resistance was increased significantly in Group I. Maximal inspiratory pressure (MIP) was significantly reduced in Group I. FRC, RV and RV/TLC ratio were increased above 120% in both groups with more significant increase in Group I. Group I showed moderate hypoxemia (PaO(2) = 54.02 mmHg) with hypercapnia (PaCO(2)= 46.65 mmHg) whereas Group II patients were mildly hypoxemic (PaO(2)= 63.78 mmHg) with normocapnia. Parameters of breathing pattern were similar in both groups. Diaphragm height index (DHI) didn't showed significant difference between groups. But there were significant correlations between DHI and RV, FRC. MIP showed significant positive correlation with airflow rates and DLCO, negative correlation with lung volumes, positive correlation with PaO(2) and negative correlation with PaCO(2). FRC also negatively correlated with Ti and Ti/Ttot. In conclusion, hyperinflation present even in the mild forms of COPD causes inspiratory muscle weakness which in return results in impairment in gas transfer.

- Abstract
We use the nebuliser therapy to achieve rapid improvement in patients with acute airway limitation. Besides, this drug is effective in asthmatic children, in elderly patients and in patients with end-stage disease who need palliative care. Nowadays nebuliser therapy is used not only for bronchodilatation but also for antibiotic and expectoration treatment. Although nebuliser therapy provides a rapid and effective treatment in airway limitation, the patients who receive home nebuliser therapy may suffer from severe and incurable infections if the hygienic conditions are not achieved. Therefore, the indications of nebuliser therapy should be precisely determined and special care should be given in the choice of the patients who will receive nebuliser therapy.

- Abstract
Dyspnea defined as an uncomfortable sensation of breathing is the main cause of disability in chronic obstructive pulmonary disease (COPD) patients. There is evidence that the underlying mechanisms of dyspnea are multifactorial. The aim of this study was to investigate these mechanisms causing dyspnea in COPD patients and the relationship between functional parameters, dyspnea scales and quality of life questionnaire. For this purpose 56 patients (11 female, 45 male) were recruited. Pulmonary function tests including airflow rates, lung volumes, maximal respiratory muscle forces, diffusing capacity, breathing pattern, arterial blood gas analyses as well as dyspnea scales MRC, baseline dyspnea index (BDI) and The Saint George Respiratory Questionnaire (SGRQ) were performed. The overall group showed moderate obstructive disease (FEV1%= 59.02 +/- 3.30) and mild hypoxemia with some air trapping (RV/TLC%= 52.00 +/- 2.00). MRC scale did not show any significant correlation with pulmonary function parameters. There was significant positive correlation between BDI and airflow rates, PImax, DLCO and air trapping. Breathing pattern parameters (Ti/Ttot, VT/Ti) also correlated with BDI. There was positive correlation between PaO2 and BDI (p< 0.001). SGRQ scores correlated significantly with FEV1, PImax, RV/TLC and P 0.1. There was also strong correlation between BDI and SGRQ scores. In conclusion, dyspnea is the result of multiple factors such as airflow limitation, decreased respiratory muscle strength, changes breathing pattern, hypoxemia, and air trapping which in turn affects quality of life in patients with COPD.
