Service quality in hotel establishments: A research in Kırşehir?

Bu çalışmanın amacı, Kırşehir ilinde faaliyet gösteren otel işletmelerinde konaklayan müşterilerin beklentileri ile hizmet kalitesi algıları arasındaki farkları ortaya koyarak, otel işletmelerinin sunmuş oldukları hizmetin kalitesini ölçmektir. Bununla birlikte araştırma, konukların demografik özelliklerini belirleyerek, bu özelliklerin beklentiler ve algılar üzerinde yarattığı farklılıkları inceleme amacı da gütmektedir. Bu çalışma üç bölümden oluşmaktadır. İlk iki bölümde literatür taranarak araştırma konusuyla ilgili ikincil verilerin analizi gerçekleştirilmiştir. Üçüncü bölüm ise alan araştırmasına ayrılmıştır. Araştırmada, literatürde hizmet kalitesi ölçümü alanında geniş yer bulan, A. Parasuraman, V. Zeithaml ve L. Berry tarafından geliştirilen, Servqual ölçeği kullanılmıştır. Araştırmada örnekleme yöntemi olarak tabakalı örnekleme yöntemi tercih edilmiş ve Kırşehir?de faaliyet gösteren on adet otel işletmesi alan araştırmasına dahil edilmiştir. Anket yoluyla elde edilen verileri analiz etmek için merkezi eğilim ölçülerinin (sayı ve yüzde dağılımları, aritmetik ortalama ve standart sapma) yanı sıra t-testi ve anova istatiksel analiz yöntemleri kullanılmıştır. Araştırma sonucunda, Kırşehir ilinde faaliyet gösteren otel işletmelerinin, konuklarının beklentilerini karşılayamadığı ortaya çıkmıştır. Yapılan istatistiksel analizler sonrasında, konukların beklenti düzeylerinin yüksek olduğu tespit edilmiş, öte yandan gerçekleşen performansa ait algı düzeylerinin ise düşük olduğu belirlenmiştir. Dolayısıyla bu işletmelerde sunulan hizmet kalitesinin konukları memnun etmediği sonucuna varılmıştır. Araştırmada ayrıca, konukların bazı demografik özelliklerinin otel hizmetlerine yönelik beklentileri ve algıları üzerinde farklılıklara yol açtığı görülmüştür. Anahtar Sözcükler: Hizmet kalitesi, hizmet kalitesi ölçümü, Servqual, otel işletmeleriThe purpose of this study is to measure service quality of the hotels operating in Kırşehir by determining the differences between the expectations and perceptions of the guests. To determine the demografic characteristics of the guests and analyze if they have any effect on expectations and perceptions is also aimed at the research. The study consists of three chapters. In the first and second chapters of the study, secondary data are examined through reviewing the related literature. In the third chapter, the primary data collected through field study, are analyzed. The Servqual scale, which is widely employed in the literature of measuring service quality, is used in the research. Stratified sampling method is choosen as sampling method and ten hotel establishments operating in Kırşehir are included in the field research. Data are gathered from the hotel guests by means of a questionnaire. Frequencies, descriptive statistics, standard deviation as well as t-test and anova analysis are used to analyze the gathered data. The results of the study indicate that the hotel establishments operating in Kırşehir can not meet the expectations of their guests. After the statistical analysis it is found that the expectation levels of the guests are high; on the other hand the perception levels are low. Therefore, it comes out that the performed service quality does not satisfy the guests. The results also show that some demographic characteristics of the guests cause differences on expectations and perceptions towards hotel services.

UYKU APNE SENDROMU OLAN HASTALARDA KARDİYOVASKÜLER HASTALIĞIN BİR GÖSTERGESİ OLAN AORTİK SERTLİĞİN EKOKARDİYOGRAFİ İLE DEĞERLENDİRİLMESİ

Aim:Obstructive characterized with intermittant obstruction of upper air tracts and leading to somnolence during all day. Aortic stiffness is associated with poor cardiovascular outcome and an early indicator of mortality and morbidity. In the present study we aimed to investigate aortic stiffness and aortic dispensability in OSAS patients. Material and methods: We selected 30 obstructive apnea syndrome patients without co-morbidities and 30 healthy individuals. All patients underwent echocardiography to measure aortic stiffness and compared to between groups. Results: There is no difference in term of age and sex in two groups. There were no difference in ejection fraction, thickness of interventiculer septum and posterior wall in between groups. Aortic strain was higher in OSAS patients compared to healthy individuals (8.64±3.41 and 5.92±2.43, p=0.024). Also, aortic dispensability was lower in OSAS patients than those with control groups (2.30±1.98 and 3.35±1.38, p=0.021). Conclusion: Aortic stiffness was increased where as aortic dispensability was decreased in obstructive sleep apnea patients without co-morbidities. Arterial stiffness could be easily evaluated by transthoracic echocardiography in OSAS patients and these patients should be evaluated in detail to follow up and threat in terms of cardiovascular diseas

Carotid-jugular arteriovenous fistula and cerebrovascular infarct: A case report of an iatrogenic complication following internal jugular vein catheterization

Central venous catheterization is frequently performed for perioperative management and long-term intravenous access. Although complications associated with central venous catheter insertion have been widely reported, there are few reports of carotid-jugular arteriovenous fistula formation. Endovascular procedures are associated with a risk of immediate and delayed thromboembolic and ischemic complications. We describe a case of a carotid-jugular arteriovenous fistula and a cerebrovascular infarct following the insertion of a double-lumen catheter for hemodialysis access. We provide recommendations for the prevention and the early detection of this iatrogenic complication

Is there any relationship between RDW levels and atrial fibrillation in hypertensive patient?

Background: Atrial fibrillation (AF) is the most common cardiac arrhythmia and increases the risk of stroke and death. Patients with hypertensive have an increased risk of developing atrial fibrillation. RDW (Red blood cell distribution width) levels are elevated in cardiovascular disorders including heart failure, stable coronary disease, acute coronary syndrome, slow coronary flow and stroke. Objective: We aimed to investigate the relation between RDW and AF in patients with hypertensive Method: We retrospectively examined 126 consecutive hypertensive patients (63 hypertensive patients with AF and 63 hypertensive patients without AF matched with age and sex Results: The mean age of the study population was 71,09± 8,50 (af group) and 70,97±8,24 (non-af group) years. RDW level was different among patients with atrial fibrillation and without atrial fibrillation.(15,13±1,58 and 14,05±1,15 p<001) . Logistic regression analysis showed that RDW and left atrial dimension were only independently risk factory associated with atrial fibrillation. (Rdw odds ratio:1,846 CI; 1,221-2,793 p<0,05). Roc curve analyses were applied to determine the cut-off point. Cut-off point was at 14,195 and Sensitive, specificity was %71,4, %56 respectively. Conclusion: RDW levels were higher in hypertensive patients with atrial fibrillation. An increased RDW level in the patient with hypertension may alert physician on developing or presence of atrial fibrillation

Argyrophilic nucleolar organizing region associated protein synthesis for cytologic discrimination of follicular thyroid lesions.

WOS: 000352110200003PubMed: 25420891Fine needle aspiration biopsy (FNAB) of the thyroid gland is an important tool for preoperative diagnosis; however, its benefit is limited for follicular lesions. Nucleolar organizer regions (NORs) are ribosomal gene regions that stain with silver (Ag) when they are active. These regions can be used to differentiate neoplastic and non-neoplastic lesions. We used a new AgNOR technique to investigate FNAB of cases diagnosed as follicular adenoma and carcinoma. Fourteen cases of follicular thyroid carcinoma (FTC) and 28 cases of thyroid follicular adenomas (FA) were stained using the silver NOR-associated protein (AgNOR) technique. One hundred nuclei per sample were examined, AgNORs were counted, and the total AgNOR area/nuclear area (TNORa/Na) ratio of each cell was calculated. We found that cases with FTC had significantly higher TNORa/Na than cases of FA. Also, cases with FTC had significantly higher AgNOR counts than cases with FA. AgNOR counting may help discriminate FTC and FA by routine cytopathology before surgery
