Compostable zein-polycaprolactone (PZ) electrospun nanofiber integrated with different concentrations of Aster yomena extract loaded halloysite nanotubes (A. yomena-HNT) as bioactive nanofibrous food packaging is reported. SEM micrographs reveal heterogeneous nanofibers.

The Role of Personality Traits Toward Organizational Commitments and Service Quality Commitments.

Service providers personality traits is one of important determinants to deliver proper service to customers to make them satisfied in service delivery. Despite numerous studies on personality traits and emotional labor, little empirical work has been conducted to investigate the causal effects of hotel middle managers' personality traits on their commitment to the hospitality industry. Thus, this study aims to examine the effects of hotel middle managers' personality on two dimensions of commitments: organizational commitment and service quality commitment meditated by emotional variables: emotional labor and emotional exhaustion.

Core/Sheath-Structured Composite Nanofibers Containing Cinnamon Oil: Their Antibacterial and Antifungal Properties and Acaricidal Effect against House Dust Mites.

This study aimed to fabricate core/sheath-structured composite nanofibers containing cinnamon oil by emulsion electrospinning and to investigate their acaricidal effect on house dust mites as well as their antibacterial and antifungal properties in relation to cinnamon oil concentration in the nanofibers. An oil-in-water emulsion, which comprised cinnamon oil and poly(vinyl alcohol) solution as oil and water phases, respectively, was used to prepare core/sheath-structured nanofibers. The morphology and the inner structure of the electrospun nanofibers were observed by scanning electron microscopy and confocal laser scanning microscopy.

Long-term Breastfeeding in the Prevention of Allergic Rhinitis: Allergic Rhinitis Cohort Study for Kids (ARCO-Kids Study).

Objectives: There is a great deal of interest in the possibility that environmental factors may influence the risk of developing allergic rhinitis (AR) in early life. We investigated the simultaneous effects of mode of delivery and duration of breastfeeding on the development of AR in children.

Methods: Data from 1,374 children participating in the Allergic Rhinitis Cohort Study for kids (ARCO-kids study) was analyzed.

Normal Mastoid Air Cell System Geometry: Has Surface Area Been Overestimated?

Objectives: The aim of this study was to emphasize the necessity of a standard in segmentation threshold and algorithm for measuring volume and surface area of mastoid air cell system (MACS).

Methods: First, we obtained axial computed tomography scans of 54 normal temporal bones from 27 subjects. Then, we manipulated Hounsfield units (HU) image data in DICOM (digital imaging and communications in medicine) files directly using our program.

Efficacy and safety of eltrombopag in adult refractory immune thrombocytopenia.

Background: Eltrombopag is a thrombopoietin receptor agonist with excellent treatment outcomes in immune thrombocytopenia (ITP). Here, we analyzed the dose of eltrombopag required to achieve and maintain safe platelet counts in Korean ITP patients.

Methods: Adult refractory ITP patients (<30,000 platelets/µL) were enrolled.

Primary sinonasal tuberculosis confined to the unilateral maxillary sinus.

Extrapulmonary tuberculosis is not rare and occurs mainly in the head and neck region. Cervical tuberculous lymphadenopathy is the most common form of extrapulmonary tuberculosis. Sinonasal tuberculosis is known to occur very rarely due to the protective functions of sinonasal mucosa.

Various tumors in the nasal vestibule.

Various types of diseases can involve the nasal vestibule. Diagnosis and treatment of a nasal vestibular mass is often challenging due to the anatomical features of the nasal vestibule. Here, we present four cases with nasal vestibular masses.

Seasonal variation in skin sensitivity to aeroallergens.

Purpose: We previously demonstrated seasonal variation in sensitization to aeroallergens in a small group of patients with exercise-induced asthma. This study was performed to confirm the relationship in a much larger population.

Methods: The charts of 1,891 patients who received allergy skin prick tests were reviewed retrospectively.

Fibrous dysplasia of the inferior turbinate.

Fibrous dysplasia (FD) is a benign skeletal disorder in which abnormally overgrowing bony lesion replaces normal bone. FD can affect one bone (monostotic form) or multiple bones (polyostotic form). The craniofacial bones are involved in about 10% of subjects with monostotic FD.

The role of mucosal immunity in fungus ball of the paranasal sinuses.

Conclusion: Increased levels of immunoglobulin (Ig)A, plasma cells, and lymphocytes without infiltration of other inflammatory cells suggest that mucosal immunity may play an important role in paranasal fungus ball.

Objectives: This study aimed to examine the nasal mucosal immune responses to fungi to understand the pathogenesis of fungus ball.

Methods: Five patients with fungus ball of the maxillary sinus were enrolled.

A schwannoma in the nasal septum.

Schwannomas of the sinonasal tract are very rare neoplasms. We present the case of a schwannoma developing in the nasal septum. The patient was a 51-year-old woman with the complaint of unilateral nasal obstruction.

Effects of dexamethasone on the expression of transforming growth factor-beta in the mouse model of allergic rhinitis.

Objectives/hypothesis: This study aimed to evaluate the effect of dexamethasone on the expression of transforming growth factor (TGF)-beta in the mouse model of allergic rhinitis.

Study Design: Female BALB/c mice were randomly assigned to four groups, including two control groups and two treatment groups.

Methods: General sensitization and local challenge were performed with ovalbumin (OVA).

Self-similar random field models in discrete space.

Self-similar random fields are of interest in various areas of image processing since they fit certain types of natural patterns and textures. Current treatments of self-similarity in continuous two-dimensional (2-D) space use a definition that is a direct extension of the one-dimensional definition, which requires invariance of the statistics of a random process to time scaling. Current discrete-space 2-D approaches do not consider scaling, but, instead, are based on ad hoc formulations, such as digitizing continuous random fields.

Statistical model of pesticide penetration through woven work clothing fabrics.

Statistical models estimating the level of protection and thermal comfort performance of woven fabrics were developed using simple fabric and liquid parameters. Eighteen woven fabrics were evaluated against three pesticide mixtures of atrazine and pendimethalin at different concentrations. Using three mixtures that represent a range of both surface tension and viscosity, percentages of pesticide penetration are measured, along with fabric thickness, fabric cover factor, yarn twist factor, yarn packing factor, solid volume fraction, wicking height, and air permeability.
