Adapting the Customer Satisfaction Index to the Lodging Industry: Foreign Customers\u27 Evaluations

As a standard form of measuring customer satisfaction, the Customer Satisfaction Index (CSI) has been utilized in many countries. By using the Korean Customer Satisfaction Index (KCSI) methodology, this study attempted to investigate foreign customers’ evaluations of luxury hotels in Seoul, South Korea. In doing so, some efforts were made to overcome the methodological problems associated with the KCSI for the lodging industry. Data for this study were collected through a mall intercept survey using a self-administered questionnaire. Precisely 783 responses, collected solely from foreign guests who had stayed at a luxury hotel in Seoul, were included in the study

Measuring Brand Equity of Restaurant Chains

Little research has been done to measure brand equity of hospitality companies. It is important for food service organizations to measure accurately their brand equity in order to manage and leverage it properly. This study attempts to measure the brand equity of casual dining restaurant chains in monetary terms using conjoint analysis

Retrieval of NO2 Column Amounts from Ground-Based Hyperspectral Imaging Sensor Measurements

Total column amounts of NO2 (TCN) were estimated from ground-based hyperspectral imaging sensor (HIS) measurements in a polluted urban area (Seoul, Korea) by applying the radiance ratio fitting method with five wavelength pairs from 400 to 460 nm. We quantified the uncertainty of the retrieved TCN based on several factors. The estimated TCN uncertainty was up to 0.09 Dobson unit (DU), equivalent to 2.687 ?? 1020 molecules m???2) given a 1?? error for the observation geometries, including the solar zenith angle, viewing zenith angle, and relative azimuth angle. About 0.1 DU (6.8%) was estimated for an aerosol optical depth (AOD) uncertainty of 0.01. In addition, the uncertainty due to the NO2 vertical profile was 14% to 22%. Compared with the co-located Pandora spectrophotometer measurements, the HIS captured the temporal variation of the TCN during the intensive observation period. The correlation between the TCN from the HIS and Pandora also showed good agreement, with a slight positive bias (bias: 0.6 DU, root mean square error: 0.7 DU)

Fermi level pinning on Si0.83Ge0.17 surface by inductively coupled plasma treatment

Effects of inductively coupled plasma (ICP) treatment on Fermi level pinning on the surface of Si0.83 Ge0.17 was studied by current-voltage and x-ray photoemission spectroscopy measurements. ICP treatment induced the growth of silicon oxide, suggesting that Si vacancies are generated under the oxide. From linear fitting of Schottky barrier heights with metal work functions, it was found that surface state density increased from 6.60?? 1012 to 1.13?? 1013 cm2 eV by the ICP treatment, leading to the pinning of surface Fermi level about EC ???0.53 eV. From this, it is suggested that the Si vacancies are the main surface states in pinning Fermi level on the ICP-treated surface.open1
