Investigando a Interação Anfitrião-Convidadono Airbnb

This study aims to examine the reviews of guests who had Airbnb experience in Mexico City, Athens, and Tokyo in terms of host-guest interaction. In this way, we intend to interpret guest's experience, satisfaction, recommend and revisit intention phenomenon in terms of depth and breadth of host's sincerity. We adopt an interpretive approach and a mixed method. That is, the study combines topic extracting technic by employing online secondary big data and explicating emerging themes and patterns. The paper highlights firstly sincerity of communication in sentences with host name emphasized. On the other hand, the host's responsive and communicative nature improves friendliness over time, which affects experience, satisfaction, recommend and revisit. Finally, Airbnb hosts are intermediator of local culture. In our research, a lexicon specific to our research topic (guest-host communication) was created by using topic extraction, Tf*Idf and named entity extraction techniques. The created lexicon can be used in other studies in this field. Furthermore, we conclude that using hosts’ name in reviews by guest an important attribute of interaction. Findings from this study provides important managerial implications for hospitality industry and Airbnb hosts who attempt to interact with guest accurately. Thence the study suggests a communication should enclose diverse and accurate information, host should pay attention to be friendly and communicative, respond as quickly as possible

A comparative study on exergetic assessment of two ground-source (geothermal) heat pump systems for residential applications

WOS: 000243984000017Ground source heat pumps (GSHPs), also known as geothermal heat pumps (GHPs), have been widely used for years in developed countries due to their higher energy utilization efficiencies than those of both conventional heating and cooling systems. However, they have been applied to the Turkish residential buildings since 1997. This study deals with the exergetic performance evaluation of two types of GSHP systems installed in Turkey based on the actual operational data. The fist one is a GSHP system designed and constructed for investigating geothermal resources with low temperatures, while the second one is a GSHP system with a vertical ground heat exchanger. In the analysis, four balance (mass, energy, entropy and exergy) equations are applied to the two GSHP systems considered for modeling purposes in a tabulated form. Exergy (second law) efficiency values for both systems are given, while exergy destructions in each of the system components are determined to assess their individual performances by presenting the potential for improvements. It may be concluded that the exergetic evaluation method presented here may be applied to other GSHP systems worldwide as a useful tool, which is a way to sustainable development.

Prevalence and risk factors of occupational asthma among hairdressers in Turkey

This study was designed to evaluate the questionnaire-based prevalence and possible risk factors of occupational asthma among hairdressers in Turkey. We investigated occupational history and respiratory, ocular, dermal, and nasal symptoms using a standardized questionnaire, evaluated worksite pulmonary function tests, and performed allergen skin testing. We then determined asthma risk factors using age and gender-adjusted logistic regression models. The prevalence of occupational asthma in hairdressers was 14.6%. The odds ratio for hairdressers in a high work intensity group was 3.6 (95% confidence interval, 1.2 to 10.9) with a significant dose-response trend (chi(2) trend = 4.875; P = 0.027). The odds ratio for occupational asthma among workers with atopy was 4.5 (95% confidence interval, 1.2 to 17.2). We also observed an excess risk of occupational asthma with allergic rhinitis and conjunctivitis. Occupational asthma did not differ among subgroups of hairdressers. We observed an important risk of occupational asthma among hairdressers. The most prominent risk factors were work intensity and atopy

Antibacterial activity of bryophyte species against Paenibacillus larvae isolates

WOS: 000409379100010This study was performed to determine the antibacterial activity of methanol extracts of 23 bryophyte species against Paenibacillus larvae isolates that cause American foulbrood diseases in honeybee larvae. The honey and larva samples were collected from nine different locations of Rize in Turkey. A total of 22 gram-positive spore-forming bacteria were isolated from the larva and honey samples. According to the results of morphological, biochemical, and molecular (16S rRNA gene sequencing) tests, 10 isolates of the 22 gram-positive spore-forming bacteria were identified as P. larvae. A total of 10 bryophyte species (Polytrichum formasum, Polytrichum commune, Calliergonella cuspitada, Calliergonella lindbergi, Metzgeria conjugata, Isothecium alopecuroides, Syntrichia calcicola, Syntrichia intermedia, Tortella densa, and Grimmia alpestris) among 23 bryophytes showed good antimicrobial activity against P. larvae isolates according the results of agar-well diffusion method and minimal inhibition concentration experiments.Scientific Research Projects Coordination Unit of Recep Tayyip Erdogan University [2015.53001.102.03.04]; Ahi Evran University Scientific Research Projects Coordination UnitAhi Evran University [PYO-MUH.4001.15.009]This study was supported by the Scientific Research Projects Coordination Unit of Recep Tayyip Erdogan University (Project No: 2015.53001.102.03.04) and the Ahi Evran University Scientific Research Projects Coordination Unit (Project No: PYO-MUH.4001.15.009)

Tuberculous meningitis together with systemic brucellosis

We present a case of a 57-year-old woman admitted with findings of meningitis. Cerebrospinal fluid (CSF) tests revealed a pleocytosis together with a low CSF glucose concentration. Empirically, antituberculosis treatment was started. Rose Bengal and Wright tests were performed to exclude brucellosis with central nervous system involvement. These tests were positive in serum but not in CSF. Antibrucellosis treatment with doxycycline and ceftriaxone was started without withdrawing the antituberculosis treatment because of the possibility of simultaneous infection with both tuberculosis and brucellosis agents. Finally, this approach was shown to be correct when tuberculosis was isolated from the culture of CSF. Clinicians in endemic regions for brucellosis should be careful while diagnosing subacute/chronic meningitis. Other possible similar etiologies such as Mycobacterium tuberculosis must be ruled out before attributing the meningitis to brucellosis

Phenotype properties and status of corticosteroid resistance among patients with uncontrolled asthma.

Background: Control cannot be achieved in some asthmatics although optimal monitoring and treatment is administered. Glucocorticoid (GC) resistance is one of the reasons of poor asthma control. We aimed to investigate GC resistance by lymphocyte proliferation suppression test (LPST) in uncontrolled asthmatics

Serum Endocan Levels on Admission Are Associated With Worse Clinical Outcomes in COVID-19 Patients: A Pilot Study.

Thrombotic and embolic complications in the cardiovascular system are evident and associated with worse prognosis in coronavirus disease 2019 (COVID-19) patients. Endothelial-specific molecule 1 (endocan) plays a role in vascular pathology. We hypothesized serum endocan levels on admission are associated with primary composite end point (mortality and intensive care unit hospitalization) in COVID-19 patients. Patients (n = 80) with laboratory, clinical, and radiological confirmed COVID-19 were included in this cross-sectional study. Ten milliliter of peripheral venous blood were drawn within 24 hours of admission to estimate serum endocan levels. Data were analyzed using SPSS version 26.0 (IBM). Patients with the primary composite end point had significantly higher serum endocan levels than patients without (852.2 +/- 522.7 vs 550.2 +/- 440.8 ng/L, respectively;P <.01). In the logistic regression analysis, only increased serum endocan levels and increase in age were independent predictors of the primary composite end point (P< .05). In the receiver operating characteristics curve analysis, we found that a serum endocan level of 276.4 ng/L had a 97% sensitivity and 85% specificity for prediction of the primary composite end point. Baseline serum endocan levels may prove useful as a prognostic factor in patients hospitalized for COVID-19
