In order to evaluate the quality of peaches non-destructively, the surface color and spectral reflectances of KURAKATAWASE, MIBAEKTO, and OKUBO cultivar were measured. Also an attempt was made to correlate reflectance characteristics and tristimulus values with quality evaluation parameters such as chlorophyll content, soluble solids, anthocyanin content, and firmness. Further analysis of the correlation coefficients showed that spectral reflectance would be effective for the quality evaluation of peaches.

Since degraded region of input image can cause false minutiae which lead to decrease identification performance, use minutiae belong to only good quality to ensure true minutiae. This paper suggests image quality measuring method with respect to local and global orientation of ridges. In order to verify a suggested method, PDFs of quality indices derived by local and global feature are computed and then, classifying each image block using Bayesian decision theory.

Purpose - Smartphone shopping malls provide customers with a variety of tangible and intangible services including web sites, web design, use convenience, information for products and shopping and various after services. Accordingly, it is needed to expand and classify service qualities based on the various services provided by smartphone shopping malls, and then analyze path structures of smartphone shopping malls' qualities → customer satisfaction → behavioral intention. The purpose of this study is to categorize the qualities of smartphone shopping mall users based on the e-SERVQUAL by Lee(2002) and the SERVQUAL by Parasuraman et al.(1988, 2005), the smartphone shopping malls' service qualities based on service quality of smartphone shopping malls used in the previous use studies, and the Website quality factors of service industry and to analyze path structure of smartphone shopping mall's qualities → customer satisfaction → behavioral intention on college students in order to confirm the system of smartphone shopping malls' qualities. Research design, data, and methodology - This study's survey was carried out on the college students of university located in northeastern of Seoul. It was from December 7 - 15, 2017, and a total of 240 questionnaires were distributed, with 228 collected. Of them, effective questionnaires used in the final study were a total of 201 except 27 that couldn't be used. In this study, empirical analysis was done with factor analysis, correlation analysis, multiple regression analysis, simple multiple regression analysis and moderating regression analysis by using Statistics Package SPSS18.0. Results - The study results are as follows: First, smartphone shopping malls' qualities were classified into six categories like customer system quality, Web design quality, convenience quality, information-offering quality, service quality, and product quality. Second, it showed that system quality, Web design quality, and information-offering quality had a positive impact on customer satisfaction, respectively. Third, it suggested that quality factors of smartphone shopping mall users had a positive impact on customer satisfaction in the order of quality, information-offering quality, system quality and Web design quality. Finally, it showed that customer service quality, product quality, and convenience quality did not have a positive impact on customer satisfaction. In addition, it said that customer satisfaction of smartphone shopping mall users had a positive impact on behavioral intention and thereby, the higher the customer satisfaction was, the higher the relations between reuse intention and recommendation intention were. Meanwhile, moderating regression analysis showed that trust did not have moderating effect in the relations between customer satisfaction and behavioral intention. The above study revealed that smartphone shopping malls' qualities were classified into six categories and it was possible to generalize after empirical analysis was made in the path structure. Conclusions - Smartphone shopping mall users consider usefulness of obtaining shopping information and quality on quick and abundant shopping information more important than access environment of smartphone shopping malls and kind services of smartphone shopping mall managers. Thereby, smartphone shopping mall marketers need to take service qualities like system quality and information-offering quality into more consideration.

This study aims to verify the effect in the estimation of hotel service quality by analyzing the influence and the interrelation of Customer Quality, Physical Quality and Service Provider quality regarding Hotel Qualify. The result of the research shows that with regard to the influence on hotel quality, service provider quality ranks most high, physical quality second, customer quality of manner third, and customer quality of appearance fourth in order. The physical factors in the interrelation among variables rank most high. This result derives from finding the fact that customer quality is an important influential factor in the constructional dimension of hotel service quality.

The purpose of this study was to investigate the influence of cooking wine's functions on food quality attributes. factor analysis, reliability analysis (Cronbach's $\alpha$), and multiple regression analysis were employed to analyze the data. The cooking wine functions were divided into 3 factors (expectation of utility, functionality, and quality enhancement). According to the multiple regression analysis of cooking wine factors to food quality, all factors had positive influences on food quality. Among the three factors, expectation of utility(=.556, p<0.001) had the most significant influence on food quality. And functionality (=.321, p<0.001) and quality enhancement(=.296, p<=0.001) also had significant effects in that order. further research should be conducted on cooking wine's utility aspects and their effects on food quality. Finally, we anticipate that the results of this study will be useful information for food-service companies.

The importance of quality logistics service to the enterprises has kept growing considering the fierce competitions. It also asks for the sound definition and the scale explaining the construct of logistics service quality. The current study attempted to identify the construct of logistics service quality and develop the scale to measure it. Various qualitative and quantitative methodologies have been employed in order to provide the solid theoretical and psychometrical foundation of the proposed scale. In so doing, the conceptual definition of Logistics Service quality has been proposed and the 127-item scale measuring the construct of logistics service quality has been developed and found to be reliable and valid.

Amid the rapidly changing constructional business conditions, the volume of BTL business sectors has expanded largely during two or three years. Especially, construction works fur educational facilities of elementary, middle and high schools has been performed by the mid-sized construction companies who are not capable of doing effective and systematic quality management while the requirements of the customers are getting higher and higher. In order to have a flexible deal with the rapidly changing business conditions and also to enhance the quality level, it is the high time to reorganize the effective quality management systeme by doing the overall analysis about the quality defects in construction site. Accordingly through the investigation about the quality defects in the construction sites of domestic educational facilities, this study will focus on what kind of quality defects show. It is aimed at providing the preliminary data for the establishment of quality management fur the construction site of the domestic educational facilities by analysing the investigation results.

Positron emission tomography-computed tomography (PET/CT) provides both functional and anatomical images of high quality non-invasively with better precision in localization than PET alone. Increase in the use of PET/CT, coupled with increasing concerns about the quality of medical services accrued the demands for accurate evaluation of system performance and quality assurance. Thus, well designed programs for performance evaluation and quality assurance are needed. Widely used protocols for performance evaluation of PET are the methods proposed by National Electrical Manufacturers Association (NEMA) in 1994 and 2001. In addition, in order to maintain high quality of PET/CT images, quality assurance programs including periodic (daily, monthly, and yearly). Therefore, in this article, the methods and present state of performance evaluation and quality assurance of PET/CT are reviewed.
